New Interactive Data Feature

“We’ve created interactive data visualizations that allow you to explore our demographic data by various geographies and characteristics,” says Anne Cahill, the county’s demographer. “By putting open data into interactive data visualizations, it is easier for you to see patterns and understand the information better than in other formats.”

The nine interactive profiles available to date include community profiles, occupations, languages spoken at home and immigrants.
