    The story so far

    Local job base moved from 345 in 2010 to 600 by 2023, with the pace of change shifting noticeably around 2014 (-0.8%/year before, +8.1%/year after). That trend is still underway as of the most recent data. Owner-occupancy has fallen 7 percentage points since 2009 (93% to 86% by 2024) — measured across non-overlapping ACS survey windows to avoid over-reading a single year's release.
