The Decline of African-American representation in unions and
manufacturing, 1979–2006

Introduction
For much of the postwar period, a higher share of African-American
workers have been in unions than workers from other racial and ethnic
backgrounds. As union representation and union coverage have declined
for the country as a whole, unionization rates for African-Americans
have fallen more quickly than for the rest of the workforce. Black
workers are still about 30 percent more likely than the rest of the
workforce to be in a union today, but as recently as the mid-1980s,
black workers were almost 50 percent more likely to be in a union or
covered by a union at their workplace. Part of the reason for the
decline in unionization rates among African-Americans is undoubtedly
related to the decline of U.S. manufacturing. For example, since the
1960s, African-Americans were more likely to work in the heavily
unionized automotive sector than white or Latino workers. As these
sectors have declined in relative importance, unionization rates for
blacks have also dropped. The overall decline in manufacturing,
however, is only part of the problem. First, since the early 1990s,
the share of black workers in manufacturing has been falling more
rapidly than the manufacturing share for the workforce as a
whole. From the end of the 1970s through the early 1990s,
African-Americans were just as likely as workers from other racial and
ethnic groups to have manufacturing jobs. Since the early 1990s,
however, black workers have lost considerable ground in manufacturing.
By 2006, blacks were about 15 percent less likely than other workers
to have a job in manufacturing. Second, even within manufacturing,
unionization rates have been on the decline, to the point where
manufacturing workers now are no more likely to be in a union than
workers in the rest of the economy (see Schmitt and Zipperer,
2007a). Meanwhile, over the last 25 years, unionization rates have
held steady in the public sector, which suggests that employer
opposition to unions, not simply economic restructuring, lies behind
the decline in overall unionization rates (see Schmitt and Zipperer,
2007b).
Findings
Our analysis of data from the Current Population Survey, the
government's most important regular source of data on the labor
market, also finds:
-
Between 1983 and 2006, the share of African-American workers who
were either members of a union or represented by a union at
their place of employment fell substantially, from 31.7 percent
of all black workers in 1983 to 16.0 percent in 2006. In 2006,
African-Americans were still more likely to be in a union (16.0
percent) than whites (13.3) and Hispanics (10.7
percent). Nevertheless, the decline in union membership for
black workers between 1983 and 2006 was sharper for blacks (down
15.7 percentage points) than it was for whites (down 8.9
percentage points) or Hispanics (down 13.5 percentage
points). (See Table 1.)
-
The share of African-Americans working in manufacturing declined
from 23.9 percent in 1979 to 10.1 percent in 2006. Whites saw
slightly smaller declines (from 23.5 percent to 11.9 percent),
while Hispanics experienced a bigger drop (from 30.2 percent to
12.6 percent). (See Table 2.)
-
Between 1979 and 2006, the share of workers in auto
manufacturing dropped for blacks, whites, and Hispanics. Blacks
suffered the biggest decline, a 0.8 percentage-point decline,
from 2.1 percentage points in 1979 to 1.3 percentage points in
2006, compared to a 0.3 percentage point drop for whites and
Hispanics. (See Table 3.)
-
Throughout the entire 1983-2006 period, black workers have made
up 13-15 percent of all union workers. Over the same period, the
share of whites in the total union workforce fell from 78.1
percent to 69.2 percent, while the share of Hispanics rose from
5.8 percent to 11.5 percent of all union workers. (See Table 4.)
-
Throughout the entire period from 1979 to 2006, the share of
African-American workers in the total manufacturing workforce
hovered around 10 percent. Meanwhile, white workers fell from
82.7 percent of all manufacturing workers in 1979 to 69.9
percent in 2006. Hispanics (and other workers) significantly
increased their representation in the manufacturing workforce
over the same period (up from 6.0 percent of manufacturing jobs
in 1979 to 14.5 percent in 2006, for Hispanics). (See Table 5.)
-
In 2006, blacks made up 14.1 percent of the auto manufacturing
workforce; whites were 73.3 percent; Hispanics, 7.6
percent. Between 1979 and 2006, the share of blacks and whites
in the total auto manufacturing workforce both fell. The share
of Hispanic and other workers, meanwhile, increased, although
remained at relatively low levels. (See Table 6.)
-
Interpreting the preceding changes in the distribution of
African-American employment and unionization rates can be
complicated since the share of African-Americans and other
racial and ethnic groups in the total workforce has changed over
time. Tables 8, 9, and 10 show the “relative
representation” of whites, blacks, and Hispanics in the
total union workforce (Table 8), the total manufacturing
workforce (Table 9), and the auto manufacturing workforce (Table
10). The simplest way to explain the calculation is with an
example. To calculate the relative representation of
African-Americans in the share of all union workers, we take the
ratio of the share of African-Americans in all union workers
(14.0 percent in 2006, in Table 4) to the share of
African-Americans in the total workforce (10.8 percent in 2006,
in Table 7). The resulting ratio is 1.30, which is greater than
1, indicating that African-Americans are
“over-represented” among union workers since there
is a larger share of African-Americans in unions than there is
in the workforce as a whole. In the same year, Hispanics made up
11.5 percent of union workers, but 13.6 percent of the total
workforce, resulting in a relative representation of 0.85, which
is less than 1, indicating that Hispanics are
“under-represented” among union workers. If a group
has the same share of workers in unions as they do in the total
workforce, then the ratio for relative representation would
equal one (which is close to the rate for whites in 2006, 0.99).
-
In 2006, African-American workers were
“over-represented” in unions (Table 8) and in auto
manufacturing (Table 10), but are actually
“under-represented” in manufacturing as a
whole. (See Table 9.)
-
The relative representation of African-Americans has been slowly
declining in unions (Table 8), manufacturing (from the
mid-1990s, Table 9), and auto manufacturing (Table 10). From the
mid-1990s on, black workers have actually been under-represented
in manufacturing, relative to the rest of the economy (Table
9). Meanwhile, white workers have held their ground in
manufacturing (Table 9), and have actually increased their
relative representation in unions (Table 8) and auto
manufacturing. (See Table 10.)
