Earlier I posted the 2010 One Year Estimate for basic demographics from the American Communities Survey for Oneida County. In addition to these 1 Year Estimates, there are 3 year and 5 year estimates put out by the Bureau for Oneida County too.
Because Herkimer County has a population of less than 65,000 people, the Census Bureau doesn't provide any 1 Year ACS data updates. Instead, Herkimer County only has the 3 Year or 5 Year estimates available.
Below are the Three Year ACS Estimates (2008-2010)for basic demographic data for Herkimer County. Housing data and Social data that can be found at the US Census Bureau website.
