MODZCTA: Modified Zip Code Areas for COVID-19 Mapping in NYC

A shapefile for mapping data by Modified Zip Code Tabulation Areas (MODZCTA) in New York City, based on the 2010 Census ZCTA shapefile. The NYC Department of Health & Mental Hygiene (DOHMH) uses these areas for mapping COVID-19 data. The dataset was last updated on May 19, III.

Use Cases

• Mapping COVID-19 case rates using MODZCTA and pop_est columns for population-adjusted analysis.
• Aggregating health data to custom geographic units using the_geom and label columns for spatial joins.
• Analyzing demographic patterns by correlating ZCTA (original zip code) with MODZCTA boundaries.
• Creating choropleth visualizations of public health metrics using the_geom geometry and MODZCTA identifiers.

Strengths

• Designed for a specific public health use case (COVID-19 mapping) by the NYC Department of Health.
• Includes a population estimate column (pop_est) for normalization.
• Provides multiple file formats (CSV, JSON, XML, RDF) for flexibility.
