Data Group Name:  popst

Description:
        State and U.S. population 1970-1992.
        This is a subset of the data in the "pop" series:
        State population totals by year without gender, age, and race
        breakdown.  See "pop" series for populations by gender, age,
        race.

Data Source(s):
        US Census: Intercensal Estimates of the Population of Counties
        by Age, Sex and Race, 1970-1980, 1980-1989, and 1990-1992.

Comments:
   The 1980 population counts were taken from the 1980-89 Intercensial
   Estimates file.
   The intercensial estimates are given at the county level.  These data
   have been aggregated to the state and national levels.
   This is a reduced version of these data which was made from the
   pop series which has a further breakdown of population by
   gender, race, and 5-year age groups.
   See the series "pop" for more information.

Usage:  To look up values of these data for a set of key variable values
        (in SAS):

        a) In your SAS program, before your data step add:

           %include 'popst.fmt';

        b) set SUPERKEY to the combination of key variable values you
           want to look up.  See "SUPERKEY=" under key variable
           description below.

        c) use a formatted put function of SUPERKEY with the data series
           format (See examples under "Usage" in detailed description of
           each data series).

Key vars:  Varname    Typ    Description
           YEAR       Num    Year
                             Min=1970   Max=1992
           STATE      Num    FIPS STATE CODE (99=US)
                             Min=1   Max=99

          SAS code to make SUPERKEY:

           SUPERKEY =(100*YEAR) + STATE;
