NYC Housing Unit Changes by Community District Since 2010

Net change in housing units for New York City Community District Tabulation Areas (CDTAs) tracks new construction, demolitions, and alterations since 2010. The dataset is aggregated from the NYC Department of City Planning's Housing Database, which is derived from Department of Buildings-approved jobs. The current version reflects data through the fourth quarter of 2025.

Use Cases

• Analyze net housing unit growth by CDTA using `comp2010` to `comp2024` columns to track annual completions.
• Compare approved (`approved`) versus filed (`filed`) construction projects to assess the development pipeline.
• Map housing unit density changes by joining `cenunits20` (2010 census count) with later completion columns on `CDTA2020`.
• Identify districts with high rates of withdrawn (`withdrawn`) or inactive (`inactive`) projects to study development hurdles.
• Calculate the share of units pending completion using `permitted` and `approved` columns against total census units.

Strengths

• Tracks housing unit changes annually from 2010 through 2024 via specific completion columns.
• Geospatial data (`the_geom`, `Shape_Area`) enables mapping and analysis by Community District.

Limitations

• Sample data unavailable, preventing verification of data distributions and null values.
• Unknown row count and total record volume limits assessment of statistical reliability.
• Data is aggregated to the CDTA level, obscuring project-level details and variation.
