This Atlas makes available for the first time Illinois poverty data by legislative district. Elected officials now have the opportunity to understand how poverty impacts their own individual districts in three key ways: education rates, poverty rates, and median incomes. The data is also provided at the county level, for townships in Northeastern Illinois and by community area in Chicago. The information in the Atlas is derived from the 2000 U.S. Census with comparisons to 1990 Census data to establish rates of change in poverty. Taken once every decade, the U.S. Census presents an important opportunity to more closely examine population characteristics. These maps offer a unique geographic display of poverty issues in Illinois.
