Frequently asked questions

What is the real (cost-adjusted) Data Scientist salary in Pennsylvania?
After BEA RPP adjustment (regional price parity index 97.4 for Pennsylvania), the real-wage equivalent is $102,998 — what the $100,320 nominal salary actually buys. Quartiles in real terms: $78,255 to $133,049.
What does the top of the Data Scientist pay scale look like in Pennsylvania?
The 90th percentile lands at $165,360. That tier typically reflects senior roles, specialty certifications, high-cost-of-living metros within the state, or union-negotiated rate cards. Below that, the P75 quartile is $129,590.
How many Data Scientists does Pennsylvania employ?
BLS OES counts 10,430 Data Scientists employed in Pennsylvania in the most recent release. Employment density relative to population determines whether wage tiers reflect a robust competitive market or a thinner labor pool.
How wide is the wage spread in Pennsylvania?
P10 to P90 spans $61,190 to $165,360. That spread captures entry-level to top-quartile pay, including specialty differentials and metro-area variance within the state.
Is Pennsylvania a 'real-wage arbitrage' state for Data Scientists?
No — Pennsylvania's RPP is close to the national 100 baseline, so nominal and real wages move roughly together. Neither an arbitrage nor a penalty state.
When does this data update?
BLS OES releases a new May reference set roughly each spring; we re-run the ETL pipeline within two weeks of release. BEA RPP refreshes annually. The last-synced timestamp at the top of this page reflects the most recent build.
Industry vs academia data scientist pay in Pennsylvania?
Academia and government research positions in {state} typically pay below the BLS data scientist median — often 20-40% lower at the assistant-professor or junior-research-scientist level.
