From the U.S. Census:
In advance of the Iowa caucuses on Feb. 1, the Census Bureau presents a variety of statistics that give an overall profile of each state’s voting-age population and industries.
Statistics include:
· Voting-age population and estimate of eligible voters (i.e., citizens age 18 and older).
· Breakdown of voting-age population by race and Hispanic origin (Hispanic origin and race alone) (race alone or in combination).
· Selected economic characteristics, including median household income and poverty.
· Selected social characteristics, including educational attainment.
· County Business Patterns (providing information on employment by specific industries).
· Statistics on voting and registration.
