The Chronicle of Philanthropy has released its 2014 “How America Gives” study. The study was based on aggregated data from 2012, the most recent year with available IRS tax data. This data was, in turn, compared with data from 2006 in order to determine percentage rates of change. Giving was tracked at the state, county, metropolitan-area, and Zip code levels.
The ranking of zip codes and counties was based on the ratio of an individual’s AGI to the total amount of their itemized charitable giving. Total amount tracked was $180 billion which, according to Giving USA accounts for approximately 80% of total giving in 2012.
