On Tuesdays, the Mayor’s Office of Transportation & Utilities (MOTU) posts a map or graphic that tells a story about transportation or utilities in the City of Brotherly Love.
Just about a year ago, MOTU mapped where Philadelphians are most likely to live if they commute to work by public transportation (you can find this map here). We updated this map with the most recent release of American Community Survey 5-year estimates AND we decided to also map it in 3-D! The 3-D model shows relative heights of Philly’s block groups based on the percent of residents who commute by public transportation.
According to the 2008-2012 ACS, 26% of Philadelphia residents who worked commuted by public transportation. While this is the total for the entire city, there are smaller subsections that have higher and lower public transportation commute rate, as can be seen in the above maps. All data for these maps was pulled from the US Census’ American Factfinder.
You may be asking yourselves, why include a 3-D map in addition to the 2-D map? In addition to looking interesting, the colors we show each have a range attached. For example, even though 90% is greater than 82%, it will have the same color green. This is where the height comes in — the height of the blockgroup shows relative percentage within the range specified by color.
