As a Population Research Librarian, I sometimes field questions about census data for individual states. Rather than wading through the Census Bureau page to find detailed data and projections on the state and local level, I often go directly to a State Data Center site. Every state has one and they are part of the Census Bureau’s State Data Center Network. Basically, these Centers pull out the relevant data for their state and make it easily accessible. I find the staff to be very professional and willing to answer questions by phone, at least in New Jersey. So…if you live in New Jersey and would like to know how much more densely populated your town was in 2010 compared to 2000, go to the New Jersey State Data Center and scroll down to the “Population Density by Municipality: 2000 & 2010” table. Have fun exploring!
