By the Numbers
How fast it's moving
Assessed-value change for the typical home. Philadelphia taxes a flat 1.3998% of value, so the bill moves with it.
The makeup of the block
Every home, plotted by size and assessed value — press play and watch the block reprice from 2016 to 2027. One bubble per house (area = lot size), colored by who owns it; a gold ring marks a material assessment exemption whose legal basis is not established by the roll. Click a bubble for its report.

Safety & quality of life
Within 200 metres of the block over the last 12 months: 156 reported crimes (about 13 a month, 35% of them violent) and 200 resident 311 requests to the city. A busy commercial corridor logs far more than a quiet residential block, so read this against nearby blocks, not the citywide total.

Who really pays
Philadelphia's 1.3998% rate applies to the taxable assessment. The OPA roll shows exemptions that can make an estimate lower than the full assessed-value scenario; this chart does not identify their legal basis.
