The Census Bureau counts prisoners as if they lived voluntarily in the communities where they are incarcerated. And though most states bar prisoners from voting, the inaccurate census figures allow state lawmakers to pad district populations when drawing legislative maps. This creates prison districts with disproportionate voting power and drains political influence from the urban districts where most prisoners live.
