United States Census Bureau. Land/Density: Population Density | State: Wisconsin, 1990 - 2012. Data-Planet™ Statistical Datasets by Conquest Systems, Inc. Dataset-ID: 001-011-003
Dataset: Population density, or persons per square mile, is a numerical method of expressing the extent to which people are clustered within a specific geographic area. Data values are calculated by dividing the total population of the entity (based on Census population estimates data) by the total land area of the entity (land area).
The files contained in this dataset are from the Census Gazetteer Files, which were extracted from the Census 2000 Summary File 1 (SF1) DVD with Software Enhancement (Product Id: V1-D00-S1S1-08-US1). Area measurement data provide the size of geographic entities for which the U.S. Census Bureau tabulates and disseminates data. Area is calculated from the specific boundary recorded for each entity in the US Census Bureau's geographic database, TIGER, which is an acronym for the Topologically Integrated Geographic Encoding and Referencing (system or database). It is a digital (computer-readable) geographic database that automates the mapping and related geographic activities required to support the Census Bureau's census and survey programs.

The United States Census Bureau is a bureau of the United States Department of Commerce. The major functions of the Census Bureau are authorized by Article 2, Section 2 of the United States Constitution, which provides that a census of population shall be taken every 10 years, and by Title 13 and Title 26 of the United States Code of Federal Regulations.
The Census Bureau is responsible for numerous statistical programs, including census and surveys of households, governments, manufacturing and industries, and for United States foreign trade statistics. The first United States census was conducted in 1790 for the purposes of apportioning state representation in the House of Representatives of the United States and for the apportionment of taxes.
