U.S. Census Connections: A Resource Guide

General reference publications and census finding aids help researchers identify sources for U.S. decennial and economic census information. This guide identifies useful resources for locating census publications at the Library of Congress and online.

Introduction

It's your America! Help the ten-year roll call--1940 census, U.S.A. [1940?] Library of Congress Prints and Photographs Division

The purpose of this guide is to assist researchers in identifying and locating selected U.S. decennial and economic census publications in the Library of Congress by connecting them to existing general reference publications and other census finding aids, in print and online, that provide additional information useful in identifying needed census reports from the very first Census of 1790 to the present day.

In the past few years the number of digitized publications has skyrocketed making it possible to find most of the historical census data online. Many of these publications can be found on the Census Bureau website as well as Hathi Trust Digital Library or the Internet Archive. Links to the digitized versions of the publications are added when available. Recent census data and publications are exclusively online—links to online resources are provided.

Please note that these reports do not include actual records with names; rather they are statistical data compilations based on the census records. The National Archives has census schedules on microfilm available from 1790 to 1940. Records with identifying information are not published until 72 years after the census day.

Although this guide lists print materials at the Library of Congress only, users should be aware of the Federal Depository Library Program that makes government information available to the public for free. Please check your local FDLP library to find census reports in print.

It is hoped that this guide will be used as a lead-in tool to resources offering additional information to aid in identifying the appropriate census data report for research needs. If you have any further questions, please Ask A Librarian.
