Philadelphia Tax Abatements Mapped

Sun, 04 Feb 2018 18:25:33 -0500

Map of 10 year Property Tax Abatements
These are controversial as they subsidized upper-middle class housing, while taking money away from the city and school district. The goal is to encourage development and long term growth in the property tax base, but the tax abatements might just be subsidizing a "back to the city" trend that is caused by external factors.

Philly Socialists and the Philadelphia Tenants Union - A Review Two Years Later

Mon, 10 Jul 2017 18:58:10 -0400

I'm reviewing the original Philadelphia Tenants Union proposal that was proposed by David Thompson and Tim Horras for the Philly Socialists in August 2015. At that time, Tim Horras was chair of the organization. And David Thompson currently is chair.

For the record, I'm currently a dues-paying, but inactive, Philly Socialists member. I was very active in August 2015 and before.

Their proposal (see below) might have been slightly modified (before adoption) to include more of a time line.

Predicting the Philadelphia District Attorney Primary - May 16, 2017

Sun, 14 May 2017 20:41:58 -0400

I have developed a very tentative prediction model for the Philadelphia District Attorney's race and the Democratic primary on May 16, 2017.

The incumbent, Seth Williams, dropped out due to corruption. This left the city with a wide-open race. The Democratic party establishment has not endorsed anyone. Instead individual Democratic leaders have spread their support among the seven candidates.

My model is based on several weighted factors. The weights are somewhat arbitrary. For instance, I would give polling more weight if there were independent polls and more polls in general.

Mapping Change in Median Household Income

Sun, 01 Jan 2017 16:18:07 -0500

Cross-posted from Energy Justice

I recently updated the Income Layer on Justice Map to use the latest 2011-2015 American Community Survey data.

You can view the data by county or by census tract (roughly 4000 people). While census tracts provide higher resolution that helps us identify areas of environmental injustice, unfortunately the confidence interval is much larger. So there is a lot of noise in the data. If you are looking at the income layer and see a random checkerboard of blue and red - that is noisy data.

As part of this process, I added a Income Change layer that shows the change in median household income between the first period (2006-2010) and a second period (2011-2015).

It is easiest to see the trend in changing income by looking at the counties. The census tract data is even noisier than the regular income data, as the confidence interval is approximately twice as large. However where there are strong trends - like gentrification in DC and Philadelphia you can easily see them at the tract level.
