The results of the 2020 Census of the United States are in...

and the City of Hammond remains the #1 most populous city in both Lake County and in the whole of Northwest Indiana! This is a title we’ve proudly held on to from the 2010 Census.

In 2020 Hammond ranks as the 8th largest municipality by population in the State of Indiana.


The 2020 Census also revealed Hammond ranks as the 10th largest suburb in the Chicago Metropolitan Area, which covers 16 counties across portions of 3 states.

Since 1790, a decennial Census has occurred to determine the population of the Country as well as provide for the apportionment of elected Representatives in the U.S. House of Representatives. All of the States use the same information to determine the districts for state legislatures, continuing to the County and Municipal level. Every ten years, Census forms are sent out to every household to help collect the basic information on the number of residents, age, race, and ethnicity.

In the intervening years, 1 in 8 households will receive the American Community Survey. The survey collects information on employment, income, education achievement levels, household characteristics such as the number of bedrooms, bathrooms etc. The American Community Survey will also provide estimates of the population between the official count every 10 years to help determine changes in the population.

The two sources work together to help determine how Federal money will be distributed to the States, and then by the States to the local governments. The State of Indiana receives nearly $18 billion annually from the Federal government to assist the state and local governments as they provide services such as education, assistance to businesses, public safety, healthcare, road improvements and housing to its residents. We’ve come a long way from the 1880 Census, which found only 699 residents in the areas that would become the City of Hammond.

In the ten years between the 2010 and 2020 Census, Hammond’s population did drop by nearly 3,000 people (from 80,830 in 2010 to 77,879 in 2020). In that same period, Hammond has become a more diverse community.

Hessville (District 6) was once again our most populous of the six Planning Districts with 18,498 residents across 6,935 occupied housing units.
