Summary of Findings

In 1992, 13.0 thousand persons were employed in the District of Columbia's
manufacturing establishments. This figure represented a decrease of 24
percent from the 1987 figure of 17.0 thousand workers.

The total value added by manufacture for the District of Columbia amounted
to $1.6 billion in 1992. This figure, along with all dollar figures in this
report, are at prices current for the year specified and, therefore, are
unadjusted for changes in price levels.  Consequently, when making
comparisons to prior years, users should take into consideration the
inflation that has occurred.

In the District of Columbia, the leading industry groups ranked by
employment were printing and publishing and food and kindred products. They
accounted for approximately 85 percent of the District of Columbia's 1992
employment. These same industry groups were the leaders in 1987 when they
accounted for approximately 80 percent of the District of Columbia's
employment.

Single-establishment companies with up to 20 employees (cutoff varied by
industry) were excluded from the mail portion of the census. The data for
these establishments (and a small number of larger establishments whose
reports were not received at the time the data were tabulated) were
obtained from administrative records of other agencies or developed from
industry averages. For the District of Columbia, these establishments
accounted for 8 percent of the total value of shipments.
