Cincinnati Neighborhood Populations From the 2020 Census

 Understanding Cincinnati's neighborhoods is a complex undertaking.  Knowing the boundaries of each neighborhood is a contested concept before any other considerations are made.  The population of each neighborhood is therefore going to have criticism. I've taken a leap and come up with an updated population summary based on my determination, down to the block level. I used a 2010 set of maps from the City of Cincinnati's website with census data breakdowns that included Tract and BlockGroup details per neighborhood.  I compared that information and made adjustments based on changes to the 2020 census that included changes to the Tract, BlockGroup and Blocks designations.

That was annoying.  Why the United States Census Bureau would change tract numbers within an old city like Cincinnati is beyond my knowledge. I'd surmise it would beyond any reasonable logic available. If you know why, don't tell, but still let me know, my hairline could use an additional reduction.  Anyway, I made my determination.  Here's what I have in alphabetical order for the population of each Cincinnati neighborhood based on the 2020 Census:


So, there are some obvious notations to point out: 1) My chart only shows 51 of the 52 Neighborhoods.  That is what they City did after the 2010 census, so I followed that pattern.  The missing neighborhood is the Heights, which is basically the University of Cincinnati Campus, but what it includes beyond that is more debated.  It is included with CUF in the chart above. 2) The block level variation comes down from two sources within the census data, the voting precinct data provided and the municipalities that split some BlockGroups.

If anyone has a variation and would like to compare data, I would be more than happy to exchange information.  Leave a comment, email me, or reach out on Twitter. 

Bonus chart: Here is the same data set, sorted in descending order by Total Population.

Update: I found a few errors and have corrected them in both charts.  Additionally, here is a comparison to the 2010 data I have.  There still could be some additional changes caused by variation in the Tract and detailed groupings.
