Wikipedia has a number of articles on this topic… here is a list of the 100 poorest counties by per capita income, and by median household income (scroll past per capita to see the counties with the poorest median household income). It’s based on 2015 census data. Median is a better statistic when looking at poverty because just the most frequent income levels get included, as oppose to outliers.
For operations we’ll need to determine logistics and a visitation strategy, e.g., group counties by state for timeline of visitation, estimate car mileage versus plane and rental car expenses, hotel expenses etc.
An additional campaign strategy (national) may focus on the top 10 poorest cities. Wikipedia has an article on these cities here, based on 2012 census data (scroll down to section 2 of the article). Note that 3 of the top 10 poorest U.S. cities are in Ohio. We might want to include these cities sooner in our Ohio campaign strategy.
Here is a link to Ohio poverty data using more recent census statistics. If you look at Ohio’s major cities, you’ll see that the Ohio cities with the highest levels of poverty are: Cleveland, Dayton, Cincinnati, Toledo, Akron, and Columbus. We’ll have to compare census changes since 2012 for certainty, but based on the increase in poverty in Ohio, it looks like we may have 4 the poorest cities in the country (given Dayton’s increased poverty).
