I'm guessing that this post is about neighborhoods in Cincinnati, Ohio. I used American FactFinder on the Census web site to find data from the 2010 Census with ages up to 110.
The files I downloaded from American FactFinder for Hamilton County, Ohio are attached. Cincinnati is located in Hamilton County, but not all the Hamilton County records are within Cincinnati.
There are 871 variables when you import the DEC_10_SF1_QTP2.csv. I dropped the variables that I didn't use, and renamed the rest to include the age categories.
* metadata CSV in download from American Fact Finder explains
* what the variable names mean. using the QT-P2 table from the
* 2010 Census for Hamilton County Ohio in this example. ;
