- Multiple residential towers completed 2016–2022 along Varick St and
  Hudson St added ~2,500 units to the immediate area.
- Growth is expected to plateau as most developable sites have been built.

## Gaps & Caveats

- Census tract boundaries do not align precisely with neighborhood
  boundaries. The tract containing 250 Hudson St also includes parts
  of adjacent blocks that may have different characteristics.
- Income data is from ACS 5-Year estimates (2019–2023) and may not
  fully reflect post-pandemic shifts.
- Housing price data combines multiple sources with different
  methodologies. A local broker's CMA would provide more precise
  comparable sales.
- Employment data is at the county (Manhattan) level, not
  tract-specific. Neighborhood-level employment is estimated.
- Population projections are based on recent trends and known
  development pipeline — actual growth depends on future zoning
  and market conditions.
