For the first time since the 2000 Census, reporters will be able to track trends at the micro level, down to the neighborhood (census tract in government lingo).

Smart newsrooms are assigning the Census story as a beat, and the Investigative Reporters and Editors (IRE) association considers it so important that IRE conducted special training to help journalists sharpen their Census skills.

Obvious stories include population shifts, aging trends, and race/ethnicity topics such as integration or segregation. We'll be able to see how all of that is shifting among large cities, suburbs, small towns, metro areas and various regions of the country.

Less obvious stories include topics such as the multi-racial population. This data will give us the first official look at how America's multi-racial population has grown and shifted since 2000 - the first time that people could select more than one race on the Census form.

In addition, the 2010 Census has a housing question that will allow reporters to track home ownership vs. renting, vacant properties, and the number of people who own their houses free and clear of a mortgage. Poynter
