In order to get the most accurate information on charities that are active, Charity at a Glance must receive word from each individual charity about their activity level. Charity at a Glance surveys are sent out to individual charities and those surveys provide Charity at a Glance with the data that is mapped out.
This survey data is used to map out the activities of charities on a county level. As Charity at a Glance expands and is able to gather data from on the ground, a clearer picture of where charities are active will come to light. For the time being, county level provides Charity at a Glance maps with the most accurate sense of where charities are active.
