Census Research Guide

A guide to understanding and locating data produced by the U.S. Census Bureau

Introduction

Along with the Decennial Census, the U.S. Census Bureau conducts two other censuses, the Economic Census and the Census of Governments.  These, in addition to the Census of Agriculture now conducted by U.S. Department of Agriculture, provide a comprehensive measure of the U.S. economy, producing industry statistics at the national, state, and local levels. 

Currently, the Census Bureau uses the North American Industrial Classification System (NAICS) to classify businesses by industry. 

Annual statistics related to business establishments and owner demographics are published through products such as County Business Patterns (CBP) and American Business Survey (ABS).  Businesses with no employees are captured separately using Nonemployer Statistics (NES) and Nonemployer Statistics by Demographic (NES-D). 

Industrial Classifications

Currently, the U.S. Census Bureau classifies businesses by industry using the North American Industrial Classification System (NAICS).  In 1997, NAICS replaced the Standard Industrial Classification System (SIC).  SIC was created in 1939. 

Economic Census

Economic Census

Currently, the U. S. Census Bureau conducts an economic census every five years, in years ending in 2 and 7.  The Economic Census is an establishment-based survey, including those that:

  • Are in operation for at least some part of the census year.
  • Are located in one of the 50 states, the District of Columbia, one of the five island areas, or associated offshore areas.
  • Have paid employees.
  • Are classified in one of nineteen in-scope sectors defined by NAICS.

Census of Governments

The Census of Governments (CoG) is a complete census of all state and local governments conducted once every five years on years ending in 2 and 7.  The Census Bureau measures three components: organization (number of governments and characteristics), employment (number of employees and payroll), and finance (revenues, expenditures, debt, and assets).

Census of Agriculture

The United States has collected agricultural data since 1840. Prior to 1997, the U.S. Census Bureau conducted agricultural censuses.  Since 1997, the U.S. Department of Agriculture performs this operation.  Like the Economic Census, the agriculture census is conducted every five years, in years ending in 2 and 7.  The Agricultural Census produces data on farms and farmers, crops, livestock, and a host of related topics. For more information on the census, go to the United States Department of Agriculture
