The Long Island Index released a report suggesting ways to improve Long Island’s economy and housing options. Accompanying the report is an interactive map that Steven Romalewski, Director, CUNY Mapping Service, and the team at the CUNY Graduate Center developed that provides historical context for the report, showing demographic change throughout Long Island over a 40 year period: 1970-2010.
The report is available at the Index’s website and the interactive maps are available here.
From Steven Romalewski's description:
The maps show population patterns by Census tract for close to 40 variables – see the categories above the map. We incorporate some helpful features such as:
• hovering over the map to see detailed charts/graphs,
• using the timeline slider (upper right) to go from one decade to the next (or any decade inbetween), and
• incorporating Census data going back to 1970 (we relied on the relatively new National Historic GIS project for the data, as well as John Logan’s “Longitudinal Tract Database” from Brown University
Some of the changes portrayed by the maps are striking – you can visualize how manufacturing jobs have dramatically fallen away, race/ethnicity patterns have been transformed, household composition is steadily changing, Long Island’s population is “ageing out”, while education levels are steadily rising though poverty is stubbornly persistent.
A separate report from Regional Plan Association discusses the implications of the maps.
