How Data Scientist Salaries Work in Lancaster
City-level wages aren't published directly by BLS for most SOC codes. We build them by anchoring to the California state-level OEWS median ($135,760) and scaling by Lancaster's composite cost-of-living index (115)[1][4]. That index combines Census ACS rent, Zillow ZHVI, BLS CPI, and AdvisorSmith / ApartmentAdvisor inputs to produce one number per metro. When BLS publishes a separate metro-level wage (MSA-level OEWS), that takes priority — a handful of large metros including New York, LA, Chicago, and DC have this coverage.
On top of the gross wage, the standard US payroll stack applies: federal income tax using 2025 IRS brackets and the $15,000 single standard deduction[8], FICA (Social Security 6.2% up to $176,100 wage base + Medicare 1.45%)[9], and California state income tax at a 6.4% effective rate ($8,968/yr on the $139,154 median)[10].
Lancaster also sits inside a larger metro labor market where commute patterns, remote-work policies, and adjacent-metro wages compete. Near-national unemployment means a balanced market — employers and candidates negotiate from roughly equal positions. Median household income in the metro is $58,200, which frames what "a good Data Scientist salary" means locally: a $$139,154 wage pays about 239% of the median household income on a single earner.
The deterministic identity: take_home = gross − federal − state − FICA − pre_tax. All math runs client-side; nothing is sent to our servers.

Methodology — How we compute this page
Wage estimate. The Lancaster median is derived from the California state-level BLS OEWS median ($135,760), scaled by Lancaster's composite cost-of-living index of 115. When BLS publishes a direct MSA-level wage for the occupation, that takes priority over the scaled state median. Percentile bands inherit the same scale factor.
Housing + rent. Median home value uses Zillow ZHVI; median rent prefers Zillow ZORI and falls back to Census ACS median gross rent. HUD Fair Market Rents (50th-percentile 2BR) are shown where HUD publishes the metro. Price-to-income and rent-to-income ratios use the estimated Data Scientistmedian (not the city's overall median household income) — to reflect the specific role-vs-city affordability picture.
Tax math. Federal tax uses 2025 IRS brackets and the $15,000 single standard deduction. FICA is Social Security 6.2% up to the $176,100 wage base + Medicare 1.45% (+ 0.9% Additional Medicare above $200,000). State tax uses California's 2026 brackets from the state DoR (mirrored via Tax Foundation where the DoR's publication is paywalled or split). Local income taxes (e.g. NYC, Portland-OR supplemental, OH municipal) are NOT included — check your municipal authority for specifics.
Cost of living. The 115index is the composite used by CalcFi's /data/cities.ts, which merges Census ACS, BLS CPI shelter, Zillow ZORI, and commercial COL estimators. The COL-adjusted salary on this page assumes the statewide RPP = 112.2(BEA) approximates the state's purchasing power; cities are then scaled relative to that.
Refresh cadence. BLS OEWS releases annually (typically March); BEA RPP releases annually in December; IRS brackets adjust in October; Zillow ZHVI/ZORI updates monthly; HUD FMR publishes annually in August for the upcoming fiscal year. The dateModified shown above auto-bumps to the most recent retrievedAt on any sourced value the page consumes.
Known limits. Metro-level OEWS coverage is partial — only ~50 large MSAs have separately published occupation wages; the rest inherit state-level estimates scaled by COL. Rent and home data may trail the real-time market by 1–3 months (Zillow) or 8–12 months (ACS). Rankings are capped to the city set in our dataset (283 metros), not every incorporated US city.
