The Geographic Names Information System (GNIS) was developed by the United States Geological Survey (USGS) to meet major national needs regarding geographic names and their standardization and dissemination. This dataset consists of standard report files written from the National Geographic Names Data Base, one of five data bases maintained in the GNIS. A standard format data file for each of the fifty States, the District of Columbia and the four Insular Territories of the United States is included, as well as a file that provides a Cross-Reference to USGS 7.5 x 7.5 minute quadrangle maps.

Each geographic entity listed in this collection is identified by a unique two-character state code and a five-character numeric place code. Areas of the United States covered are the 50 states, the District of Columbia, and all outlying territories with significant self-administration (American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, Trust Territory of the Pacific Islands, and the Virgin Islands).

Functioning general-purpose governmental units were the focus of this dataset. This aggregate data collection includes the name of each governmental unit, per capita income in 1979, total population as of April 1, 1980, per capita income estimates for 1981, and July 1, 1982, population estimates.

This data collection is a component of Summary Tape File (STF) 3, which consists of four sets of data files containing detailed tabulations of the nation's population and housing characteristics produced from the 1980 Census. The STF 3 files contain sample data inflated to represent the total United States population. The files also contain 100-percent counts and unweighted sample counts of persons and housing units.

Data gathered from a variety of federal agencies and private organizations are contained in this collection which provides county statistics. Included in CO_STAT 1 are all data for counties published in the 1983 County and City Data Book and the 1982 State and Metropolitan Area Data Book, as well as a number of statistics not previously published. There are several levels of data (e.g., persons, housing units, and local governments).

MARF is the 1980 Census counterpart of the Master Enumeration District List (MEDList) prepared for the 1970 census. It links state or state equivalent, county or county equivalent, minor civil division (MCD)/census county division (CCD), and place names with their respective geographic codes. It is also an abbreviated summary file containing selected population and housing unit counts.

This data collection contains a stratified 1-percent sample of households, with separate records for each household, each "sample line" respondent, and each person in the household. These records were encoded from microfilm copies of original handwritten enumeration schedules from the 1950 Census of Population. Geographic identification of the location of the sampled households includes Census regions and divisions, states (except Alaska and Hawaii), Standard Metropolitan Areas (SMAs), and State Economic Areas (SEAs).

The 1940 Census Public Use Microdata Sample Project was assembled through a collaborative effort between the United States Bureau of the Census and the Center for Demography and Ecology at the University of Wisconsin. The collection contains a stratified 1-percent sample of households, with separate records for each household, for each "sample line" respondent, and for each person in the household. These records were encoded from microfilm copies of original handwritten enumeration schedules from the 1940 Census of Population.

Summary Tape File 4 consists of three sets of computer-readable data files containing highly detailed tabulations of the nation's population and housing characteristics produced from the 1980 Census. The files contain sample data inflated to represent the total United States population. The files also contain 100-percent counts and unweighted sample counts of persons and housing units. This series is comprised of STF 4A, STF 4B, and STF 4C. All three series have identical tables and format.

The Public Use Microdata Samples (PUMS) contain person- and household-level information from the "long-form" questionnaires distributed to a sample of the population enumerated in the 1980 Census. The B Sample containing 1-percent data, consists of a file for each state and an additional file for households and persons residing in metropolitan areas that are too small to be separately identified and/or that cross state boundaries.
