Abstract
Vital registration data for 1985 were used to
compute age-specific risks of death and average
years of life remaining at a series of birthdays
spanning the life cycle. Regardless of race, sex,
or county of residence, infancy was the age group
with the greatest risk of dying before middle
age. Metro black males had the shortest life
expectancy at birth (63.22 years) and white
females residing in nonmetro-adjacent-to-metro
counties had the longest (78.88 years), at least
partly because the former had the highest
homicide rates and the latter had the lowest. The
shorter life expectancies of all metro blacks
"crossed over" and exceeded those of
metro whites at age 75 for men and 80 for women,
since blacks at these advanced ages became less
likely to die from heart diseases, cancers, and
cerebrovascular diseases. While contrasts could
not be made between metro and nonmetro blacks
(due to their sparse numbers in the latter
counties), whites had the longest life
expectancies at almost all birthdays if they
lived in nonmetro counties bordering metro
counties.

Project # No. 3283S on "Infant Mortality in
Michigan." I thank Jean Kayitsinga for
assistance in computer programming and Lawrence
Busch for constructive commentary on an earlier
draft. I obtained the enumeration of births and
deaths according to age, sex, race, and county of
residence in 1985 from the Michigan Department of
Public Health. The mid-1985 population estimates
by age, sex, race, and county were computed by
Dr. Chingli Wang of the Department of Management
and Budget.
Introduction
Most Americans will normally use what
resources they can to prevent, or recover from,
illness. But material and nonmaterial resources
are not dispersed evenly in the population. Thus,
differences in mortality reveal people's relative
success in gaining those advantages that promote
health or recovery.
Life span should be distinguished from
longevity. Life span is the oldest age to which
the human body can possibly survive under ideal
conditions. Because ideal conditions never
prevail at all times even for the most privileged
people, life span cannot be measured directly.
The most extreme estimate of the human life span
proposed in the recent literature was the age
beyond which only 0. 1 % of the population
survived. From this definition, U.S. mortality
rates of 1985 implied that the human life
span is 108 years (Wade, 1988).
Longevity is the actual rate of survival
achieved by a population, given the risks of
death it faces from external and internal causes.
Examples of external (exogenous) causes of death
are communicable diseases, homicides, and motor
vehicle accidents; examples of internal
(endogenous) causes are those associated with the
breakdown of tissues: heart diseases, cancers,
and cerebrovascular diseases. Since the
vulnerability to external and internal causes of
death varies with age, the actual average age at
death in a population is a combined function of
the separate probabilities of death at each age
across the human life cycle. For newborns (at
exact age 0 years), this average represents the
life expectancy at birth, the most commonly used
index of longevity for a population.
The current study used data from death
certificates filed for residents of Michigan for
1985 to calculate the conditional probabilities
of surviving to each age group and then dying
within it. These age-specific risks of death were
then used to compute an estimate of longevity:
the average number of years of life remaining
(life expectancy) for someone reaching an exact
age x years. To illustrate how these averages
varied by sex, race, and Michigan county of
residence, the life expectancy at each exact age
x years was calculated separately for these
factors (see Appendix for details of the
calculations). The variations occurred because
the incidence of poverty differs by sex, race,
and county of residence, because poverty blocks
access to the health-care delivery system, and
because the medical system itself is imperfect.
The sparseness of the population in many
Michigan counties meant that some five-year age
groups yielded no observations of deaths in 1985.
Therefore, the 83 counties were grouped into
three residential categories: the 23 metropolitan
counties; the 18 nonmetropolitan counties
adjacent to the metropolitan; and the 42
nonmetropolitan counties nonadjacent to the
metropolitan.(2) These categorizations allocated
81 % of the 8,966,722 residents of Michigan in
1985 to the metropolitan counties. The other 19%
of the population were almost evenly split
between the nonmetro counties adjacent to the
metro counties (9.53%) and the more remote
nonmetro counties (9.47%).
(2)The county designations of
"metro" and "nonmetro" are
those established by the U.S. Bureau of the
Census on June 30,1983, to reflect the results of
the 1980 Census of Michigan.
Economic data from the 1980 Census of Michigan
showed that these three residential groupings
followed a gradient of declining per capita
income and increasing percent of persons below
the poverty line with remoteness from the
metropolis (1979 per capita incomes were $7635 in
metro counties, $6149 in adjacent nonmetro
counties, and $5570 in nonadjacent nonmetro
counties; the respective percentages below the
poverty line were 10.13%,11.15%, and 12.52%; see
U.S. Bureau of the Census, 1983: Tables 180 and
181). In 1980, the number of Doctors of Medicine
(M.D.s) per 100,000 residents was greater in
metro counties (159) than in the adjacent or more
distant nonmetro counties (57 and 99,
respectively).(3) While adjacent nonmetro
counties also contained the lowest ratio of
hospital beds per 100,000 residents (323), this
ratio was highest in the more remote nonmetro
counties (489) and intermediate in the metro
counties (460). Consequently, these three
classifications of Michigan counties represented
meaningful and distinct clusters of economic
advantage and availability of health care.
(3)The number of licensed M.D.9 was 11,791 in
metro counties, 470 in adjacent nonmetro
counties, and 821 in nonadjacent nonmetro
counties in 1980 (Michigan Department of Public
Health, 1980). To compute the ratio of physicians
per 100,000 residents, the number of licensed
M.D.s was divided by the 1980 Census count for
that county type; and the quotient was multiplied
by 100,000. The 1980 Census count was 7,399,212
people in the metro counties, 831,390 people in
adjacent nonmetro counties, and 826,807 people in
nonadjacent nonmetro counties (U.S. Bureau of the
Census, 1983).
Findings
Age
Age had a curvilinear effect on the
probability of dying in Michigan. For example,
for every 100,000 white males born to
metropolitan mothers in 1985, about 1046 would
probably die before the first birthday (Table
1A). Their probability of death would drop with
the first birthday and reach a lifetime low of
about 132 deaths per 100,000 white males reaching
ages 5-9 years (Table 1A). At the tenth birthday,
the probability of death would again rise but not
surpass its level during infancy until ages 40-
44. These relationships highlight two important
facts: that the risk of death before middle age
is highest during infancy (age 0 years); and that
ages 5-9 years are the safest for males in
metropolitan counties of Michigan.
With a few important exceptions, these age
patterns in the risk of death were repeated for
white females, black males, and black females
(Tables 1 A and 1B). One exception was that for
metropolitan females. Their lowest risk of death
was at ages 10-14, where 101 white females and
114 black females would die out of every 100,000
females of that racial group reaching age 1 0.
The earlier "bottoming out" of the
probability of dying in a particular age group
for metro males (at ages 5-9) than metro females
(at ages 10-14) showed that males were more
likely than females to die in adolescence and
young adulthood from such avoidable causes as
homicide and motor vehicle accidents (National
Center for Health Statistics, 1988a).
Secondly, for white male residents in
Michigan, the age grouping with the lowest
probability of dying was younger in metro
counties (ages 5-9) than in nonmetro counties
(ages 10-14) (cf. Tables 1A and 1B). Adolescent
males were safer in nonmetro than in metro
counties, for the rate of homicidal mortality was
greatest in metro counties, intermediate in
nonmetro counties nonadjacent to them, and lowest
in nonmetro counties adjacent to metro counties
(Table 3). As a result, the expectation of life
at birth for white males was shortest in metro
counties (71.65 years), intermediate in nonmetro
counties nonadjacent to metro counties (71.78
years), and longest in nonmetro counties adjacent
to metro counties (71.81 years) (Tables 2A and
2C). These differences in life expectancy at
birth are very smart but nonetheless real: they
cannot be attributed to sampling error since they
are not based on a population sample.
Thirdly, black males had an earlier-than usual
age group (ages 30-34) in which the probability
of dying in adulthood surpassed the probability
of dying in infancy. For every 100,000 black
males born to metro Michigan mothers, 2680 would
die in infancy. That risk of death would not be
met or exceeded again until ages 30-34, whereat
3358 of every 100,000 black males turning 30
years old could expect to die before turning 35
years old (Table 1 A).
Black males face a much higher death rate from
homicide than do white males, white females, or
black females (48.4, 8.2, 2.9, and 11.0 murders
per 100,000 people in that race/sex grouping,
respectively, in 1985; National Center for Health
Statistics, 1988a: Table 1-8) and witness its
peak at ages 30-34 (94.7 murders per 100,000
black males aged 30-34; see National Center for
Health Statistics, 1988a: Table 1-8). An analysis
of black males' mortality could not be done for
nonmetro Michigan counties due to the very small
number of blacks living there. But certainly, the
death rate from homicide is
much lower for all population subgroups in
nonmetro Michigan (Table 3), since crimes against
property are more common than crimes against
persons in sparsely populated areas (Rogers et
al., 1988).
Sex
After age, sex was the next most important
risk factor for mortality in Michigan. Reasons
given for the greater survival of females over
males of the same age have been the protective
effect of a female hormone, estrogen, and the
lesser tendency of women to smoke tobacco
(Epstein, 1965; Retherford, 1975). It is
noteworthy that despite the social disadvantages
of color, black females had a longer life
expectancy at every age than did white males in
metro Michigan counties (Table 2A).
The male disadvantage in survivorship varied
by race. For example, within metropolitan
counties, the "gender gap" in life
expectancy at birth favored white females by 6.80
years (= 78.45 - 71.65) and black females by 9.91
years (= 73.13 - 63.99) (Table 2A). Obviously,
black women residents of metro counties faced a
higher risk of widowhood if they married black
men of their same age or an older age.
One might expect that the gender gap would be
narrowest in the nonmetro counties adjacent to
metro counties, since these nonmetro counties
have already been shown to have the longest life
expectancies for males of all ages. Somewhat
surprisingly, the gender gap in white mortality
was widest in such counties (7.07 years = 78.88 -
71.81; see Table 2C). This relationship arose
because white women benefited more than white men
from the healthful advantages of fife in a
nonmetro county adjacent to a metro county. As
previously mentioned, life expectancies could not
be computed for black residents of nonmetro
counties due to their scarcity outside metro
areas.
Race
The odds of an infant's death vary by its
mother's marital status at birth and its sex (a
child born to an unwed mother and a male child
have greater odds of death in infancy). Yet the
odds that a child will be born to an unwed mother
are much greater if it is black than if it is
male. Therefore, in infancy, race had a larger
impact than sex on the mortality of Michigan
residents in 1985. Among metro residents, black
males had the greatest probability of death in
infancy (2680 deaths per 100,000 live births),
followed by black females (1769 deaths per
100,000 live births), white males (1046 deaths
per 100,000 live births), and white females (777
deaths per 100,000 live births) (Table 1A).
Nevertheless, the detrimental impact of being
black on life expectancy (unlike that of being
male) wore off over the life cycle. Consider the
life expectancies for residents of metro counties
(Table 2A). Among metro males, whites had longer
Life expectancies than blacks through age 69
years; at exact age 70, their Life expectancies
became nearly identical (for white men, 11.25
more years of life; for black men, 11.17). At
exact age 75 years, the life expectancy for black
men "crossed over" to exceed that for
white men. The life expectancies became almost
equal for black and white metro women at the 75th
birthday (11.69 and 11.71 more years for black
and white women, respectively; Table 2A); and at
the 80th birthday, the life expectancy for black
metro women crossed over and exceeded that for
white metro women. In the U.S. at large, black
superiority for either men or women in the
average number of remaining years of life is not
reached until a later age: the 85th birthday
(National Center for Health Statistics, 1988a:
Table 6- 1).
The racial "crossover" from black
inferiority to black superiority in life
expectancy at advanced ages has been noted by
other researchers. Nam et al.(1978) concluded
that the greater social and economic hardships
suffered by black people in early and middle age
allow only blacks with the strongest
constitutions to survive until old age but
simultaneously permit white people with weaker
constitutions to live so long. Manton (1980)
seemed to agree when he wrote that elderly blacks
are more likely to die from single causes; and
elderly whites, from multiple chronic diseases.
Put simply, white bodies are
more likely to wear out and die from multiple
organ failures.
What causes of death can best explain the
switchover from white superiority to black
superiority in survivorship at older ages in
Michigan (75 years for Michigan men and 80 for
Michigan women)? The percentage of deaths from
diseases of the heart and the cerebrovascular
system change from lower to higher for whites
than for blacks of both sexes on the 75th
birthday (Table 4). Also, the percentage of
deaths from breast cancer are lower for white
Michigan women than for their black counterparts
before age 55 and become higher for white
Michigan women thereafter (Table 4). Notably,
national rates of death from identifiable
diseases in 1985 were greatest for heart
diseases, cancers, and cerebrovascular diseases,
in that order (National Center for Health
Statistics, 1988a: Table 1-7).
County of Residence
At all birthdays along the life cycle, life
expectancies for white males were longest in the
nonmetro counties bordering on metro counties
(Table 2C). The life expectancies for white males
in the more distant nonmetro counties were
superior to those of their metro counterparts
only until the 30th birthday, at which, with two
exceptions, the relationship was reversed (Tables
2A and 2C). The threat to survivorship of white
males of prime laborforce ages in the remote
nonmetro counties may
reflect, in part, the dangers of agricultural
work, which has one of the highest occupational
fatality rates due to the heavy farming equipment
(Lansing State Journal, 1990). However,
accidental on-the-job deaths to farmers can be
only a small part of the story, since the rural
farm population of Michigan represented only 6.5%
of the state's rural population, according to the
1980 Census of Michigan. More important reasons
why the life expectancies for middle-aged and
elderly white males were shortest in the remote
nonmetro counties were their high death rates
from heart diseases, malignant neoplasms
(cancers), and cerebrovascular diseases (Table
3). Since cardiac and cerebrovascular diseases
usually remain chronic health threats after
initial onset, preventive medical care is the
most effective way to reduce mortality from these
causes. However, the low per capita incomes and
the high rate of poverty in the remote nonmetro
counties obstruct the purchase of preventive
medical services.
Access to health care in the remote nonmetro
counties has been hindered by the very federal
laws meant to help the poor (Medicaid) and the
elderly (Medicare).(4) When laws calling for
Medicare and Medicaid were passed in the late
1960s, the plans were to reimburse hospitals and
doctors on a fee-for-service basis. However, in
1983, Medicare started a Diagnostic Related
Grouping (DRG) system in which hospitals were
reimbursed a fixed payment according to the
patient's diagnosis; and Medicaid shifted to a
fixed reimbursement procedure in 1985. The
systemic contradiction is that nonmetropolitan
hospitals and physicians are now being reimbursed
according to a lower pay scale than are
metropolitan hospitals and physicians, although
nonmetro people are more likely to be poor and
less likely to have health insurance than metro
people are (McManus and Newacheck, 1989). Also,
the nonmetro poor are more likely than the metro
poor to live in a married-couple household (Rural
Nutrition and Health, 1989); and in Michigan,
such households are automatically disqualified
for Medicaid. Therefore, nonmetro residents in
Michigan are less able to cover the fee for
medical service by any means (Medicare/Medicaid
reimbursement or health insurance).
(4) In 1985, the concentrations of white
elderly Michiganian males (aged 65+ years) rose
from 9.03% in metro counties to 10.35% in
adjacent nonmetro counties to 13.53% in
nonadjacent nonmetro counties; and this
relationship was true, also, for white
Michiganian females (13.27%,13.59%, and 17.23%,
respectively).
An alternative to nonmetro poor and elderly
people is to forego medical service except in
emergencies. Indeed, the annual number of
emergency visits per hospital has risen more
sharply for nonmetro than metro hospitals in
Michigan since 1983. Admissions per hospital have
declined more sharply in nonmetro counties of
Michigan not only because nonmetro people have a
harder time paying for hospitalization but also
because metro hospitals have lured some of them
away (Stevens, 1989). Because these arrangements
make curative rather than preventive medicine a
higher priority for the poor and
the old, who disproportionately live in the
remote nonmetro counties, the death rates from
such ailments as heart diseases, cancers, and
cerebrovascular diseases are much higher in the
distant nonmetro counties (Table 3).
For at least two reasons, the life
expectancies of whites in metro counties fell
behind those in the adjacent nonmetro counties in
almost all age groups. The rate of homicidal
mortality was highest in metro Michigan counties
(Table 3). Likewise, Mexican Americans tend to
live in metro counties of the state and tend to
have poorer survival rates than do other white
people (Eberstein and Pol, 1982; U.S. Bureau of
the- Census, 1982: Tables 23 and 51). Because
Wayne County (of which Detroit is the county
seat) had 31 % of the Mexican Americans in
Michigan (according to the 1980 U.S. Census) and
70% of the homicides in the state in 1985,
exclusion of Wayne County from the analysis
should increase the life expectancies observed in
the remaining metropolitan counties (U.S. Bureau
of the Census, 1982: Tables 23 and 51; National
Center for Health Statistics, 1988b: Table 8-9).
Indeed, after Wayne County was removed, the life
expectancy at birth was highest for white males
if they lived in one of the other 22 metro
counties (72.20 years, Table 2B); and the life
expectancy at birth for white
females (78.86 years, Table 2B) nearly matched
that for white females in adjoining nonmetro
counties (78.88 years, Table 2C). The life
expectancy at birth for black males rose almost
three years (from 63.22 years to 66.06 years)
when Wayne County was excluded from the
metropolitan group; and the life expectancy at
birth for black females increased nearly one year
(from 73.13 years to 74.11 years; compare Tables
2A and 29). Therefore, the reduction of life
expectancies by homicide and inner-city poverty
in Wayne County was most visibly the black
population.
Motor vehicle fatalities were the only cause
of death specified in Table 3 with highest rates
for residents of the nonmetro counties adjacent
to metro counties. A possible reason is that
nonmetro residents may commute more regularly and
farther to work and recreation if they five next
to metro counties.
Conclusions
Longevity in Michigan should be judged from a
national perspective. For the 81 majority of
Michiganians living in metropolitan counties in
1985, the life expectancy at birth was
one-quarter of a year shorter for white males and
white females, 0.37 year shorter for black
females, and 2.08 years shorter for black males
than for the same race-sex grouping at the
national level. An important reason for the
longevity gap was a disproportionate exposure to
inner-city poverty and homicide in Wayne County,
of which Detroit is the county seat. Indeed the
life expectancy at birth in the other 22 metro
counties of Michigan was longer by 0.3 year for
white males, 0.16 year for white females, 0.76
year for black males, and 0.61 year for black
females than for the same race-sex grouping at
the national level. Obviously, the reduction of
crime against persons in Detroit would increase
the longevity of metropolitan residents of the
State of Michigan. While the data did not permit
a distinction between whites with and without
Mexican origins, it is likely that a
disproportionate amount of premature mortality
among whites in Wayne County occurred to Mexican
Americans. Premature mortality among the poor
residents of ghettos and barrios can be
alleviated by liberalizing the qualifications for
Medicaid, which is currently denied to households
consisting of married couples or earning more
than 60% of the income defining the poverty line.
In addition, language barriers may impede
communication between medical staff and those
they serve, particularly when patients have very
low levels of education or speak English poorly
or not at all.
Another disadvantaged group was white males
aged 30 or more in nonmetro counties nonadjacent
to metro counties. These remote nonmetro counties
had the highest rate of poverty and the lowest
per capita income of the three sabers in the
state. Ironically, the number of hospital beds
per 100,000 residents was greatest in these
remote nonmetro counties; and the number of M.D.s
per 100,000 residents was much greater than for
the nonmetro counties contiguous to metropolitan
counties. However, the presence of a healthcare
delivery system is insufficient to postpone
mortality when people are too poor to purchase
health care.
Appendix. Method of Estimating
Longevity
In order to
measure mortality in Michigan, the author used
death and birth certificates to count these vital
events by age, race, sex, and county of residence
in the state in 1985. For all age groups above
infancy, death rates were computed as the ratio
of the number of deaths in a particular
age-race-sex-county subgrouping to the mid-year
population estimate for that same subgrouping.
The death rates were then converted into
probabilities of dying in the various age groups
by means of the Barclay method (Barclay, 1958).
For infants, the probability of dying before the
first birthday was the infant mortality rate;
i.e., the ratio of the number of infant deaths to
the number of live births in that race-sex-county
group in 1985. The probabilities of dying in
various age groups between infancy (age 0 years)
and 85+ years, inclusive, were then used to
compute life tables by the Barclay method
(Barclay, 1958). These fife tables gave the
average number of additional years that could be
expected by a hypothetical infant of a certain
sex born to a mother having a certain race and
type of residential county in Michigan, if that
child faced all of the age- specific
probabilities of death that prevailed in Michigan
in 1985. These averages, which shall be called
the "life expectancies at exact ages
x," will hold true for the death rates
prevailing in Michigan in 1985 do not change.
