Data Services Staff compiles, maintains and monitors a vast amount of current and historical demographic data at various geographic levels for the five-county Bi-State Region, states of Illinois and Iowa and the Nation. To access demographic data for the Region, please use our Data Portal website, GreaterQCRegionData.org. Or, to access multiple data sets and/or multiple geographies within the Nation, such as census blocks, tracts, voting districts, cities, counties and school districts, visit the Census’ American Factfinder or please contact our Data Services Staff.
Data Services Staff compiles, maintains, and monitors a variety of current and historical data related to economy and employment tracked at local, regional, state, and national levels, including labor force, monthly employment and unemployment, major employers, Consumer Price Index (CPI), and ACCRA Cost of Living comparisons. Bi-State staff also conducts the ACCRA Cost of Living Survey for the Quad Cities Metro Area.

The U.S. Census counts every resident in the United States. It is mandated by Article I, Section 2 of the Constitution and takes place every 10 years. The data collected by the decennial census determine the number of seats each state has in the U.S. House of Representatives and is also used to distribute billions in federal funds to local communities.
Staff assists with preparation for and promotion of the decennial Census, and compiles, maintains and monitors current and historical Census data at various geographic levels for the five-county Bi-State Region, states of Illinois and Iowa, and the Nation. Users can access this data on our Data Portal, GreaterQCRegionData.org. Or, to access multiple data sets and/or multiple geographies within the Nation, such as census blocks, tracts, voting districts, cities, counties and school districts, visit the Census’ American Factfinder: http://factfinder2.census.gov.

2010 Census Demographic Profile Summaries (DP-1) for each county and municipality in the Region are also available.
2000 Census Demographic Profile Summaries (DP-1) for each county and municipality in the Region are also available.
The American Community Survey (ACS) is an ongoing survey that provides data every year -- giving communities the current information they need to plan investments and services. Information from the survey generates data that help determine how more than $400 billion in federal and state funds are distributed each year.
Data services staff are well-versed in the wealth of the American Community Survey data available and monitors a large store of ACS data describing the socioeconomic characteristics of the Region (or any part within). Popular data requests include population, race and ethnicity, ancestry, age, sex, family, housing, income, poverty, education, language, commuting to work, employment, veterans status. Our Data Portal, GreaterQCRegionData.org also has data for the five-county Bi-State Region, States of Illinois and Iowa, and the Nation. Or, to access multiple data sets and/or multiple geographies within the Nation, such as census blocks, tracts, voting districts, cities, counties and school districts, visit the Census’ American Factfinder: http://factfinder2.census.gov.
For additional information on the ACS, please contact our Data Services Staff.
Guidance for ACS Data Users
Three tips for using American Community Survey (ACS) data
1. The 2010 Census shows the number of people who live in the U.S. and the American Community Survey shows how people live.
• Use data from the American Community Survey to obtain demographic, social, economic, and housing characteristics.
• Use numbers from the 2010 Census to obtain counts of the population and their basic characteristics (sex, age, race, Hispanic origin, and homeowner status).
• Use data from the Census Bureau's Population Estimates Program in the years between censuses. The Census Bureau's Population Estimates Program produces official population estimates for the nation, states, counties, cities and towns, plus housing unit estimates for states and counties.
2. All American Community Survey data are estimates.
• The Census Bureau collects American Community Survey data from a sample of the population in the United States and Puerto Rico--rather than from the whole population. All ACS data are survey estimates. To help you interpret the reliability of the estimate, the Census Bureau publishes a margin of error (MOE) for every ACS estimate.
3. American Community Survey collects and releases data by the calendar year for geographic areas that meet specific population thresholds as follows:
• Populations of 65,000 + ACS 1-year estimates
• Populations of 20,000 + ACS 3-year estimates
• Populations of almost any size ACS 5-year estimates
• American Community Survey 1-, 3-, and 5-year estimates are period estimates, which means they represent the characteristics of the population and housing over a specific data collection period. Data are combined to produce 12 months, 36 months or 60 months of data. These are called 1-year, 3-year and 5-year data.

The U.S. Census Bureau Population Estimates Program (PEP) produces estimates of the population for the United States, its states, counties, cities, and towns, as well as for the Commonwealth of Puerto Rico and its municipios. Demographic components of population change (births, deaths, and migration) are produced at the national, state, and county levels of geography. Additionally, housing unit estimates are produced for the nation, states, and counties.
These estimates are used in federal funding allocations, as survey controls, as denominators for vital rates and per capita time series, and as indicators of recent demographic changes. With each new release of annual estimates, the entire time series of estimates is revised for all years back to the last census. All previously published estimates are superseded and archived.
Population estimates for the Counties and Cities in the Bi-State Region can be found on the Data Portal at GreaterQCRegionData.org.
