DISTRICT OF COLUMBIA SUMMARY OF FINDINGS

     This report provides results from the 1992 Census of Construction
     Industries for the District of Columbia.  The report includes data for
     construction establishments with payroll and shows limited data for
     establishments with no payroll (nonemployers).  (Establishments with
     no payroll are, for the most part, companies owned and operated by a
     single person.)

     During 1992, there were 1,137 establishments in the District operating
     in the construction industries.  These establishments accounted for $1.0
     billion in total dollar value of business done.

     Most of the 1,137 construction establishments were small.  Of the total,
     804 were nonemployers, and over half of the employer establishments
     had less than 5 employers.  The 181 construction establishments with 5
     employers or more, while representing only 16 percent of all
     establishments, accounted for more than 95 percent of the total dollar
     value of business done.

ESTABLISHMENTS WITH PAYROLL

     During 1992, the establishments with paid employees accounted for
     $1.03 billion in total dollar value of business done.  Of this amount,
     $1.02 billion were for the value of construction work.  Their payments
     for construction work subcontracted to others amounted to $460 million,
     leaving net value of construction work of $558 million.  In addition,
     these establishments paid out $243 million for the cost of materials,
     fuels, power, rental of equipment and buildings, and the cost of selected
     purchased services.  Value added for 1992 was $351 million.  (See
     CC92.EXP for explanation of terms.)

     There were 333 establishments with total employment averaging 6,954
     during the year.  Total payroll for 1992 was $215 million. 

     Since the data in this report covering employer establishments are
     estimated from a sample survey, they are subject to sampling variability,
     as well as errors of response and nonreporting.  The relative standard
     errors shown in the tables are measures of sampling variability. 
     Descriptions of the sampling, estimating procedures, and data reliability
     are included in CC92.MTH (Methodology).

ESTABLISHMENTS WITHOUT PAYROLL

     During 1992, there were 804 establishments with no payroll classified
     as construction.  According to administrative records of the Federal
     Government, their dollar value of business done during 1992 was $18.4
     million.  Most of these establishments, about 81 percent, were special
     trade contractors.

     For the establishments without payroll, only information on total value
     of business done was available from administrative records.  Statistics
     on establishments without payroll are shown in file CC92A1 (Summary
     statistics with and without payroll, 1992-1987).
