Pup Census: published aggregates ================================ What this is ------------ Aggregate counts and rates for 302,227 individual dogs, derived from New York City dog license records. Three files: names.csv 3,593 names carried by at least 10 licensed dogs breeds.csv 123 breeds with at least 150 licensed dogs neighborhoods.csv 82 ZIP codes with at least 1,500 licensed dogs Source and attribution (required) --------------------------------- Source: NYC Department of Health and Mental Hygiene, via NYC Open Data Dataset: https://data.cityofnewyork.us/Health/NYC-Dog-Licensing-Dataset/nu7n-tubp Version: data as retrieved 2026-08-21 License: NYC Administrative Code 23-502(d): no license requirement or restriction on use; source, version and modifications to be identified. If you republish any of this, you must identify the source, the version and the modifications, as the license above requires. That condition passes to you. Modifications made by Pup Census -------------------------------- - License renewals deduplicated to individual animals - Names normalized for case and punctuation; placeholder names removed - Breed free text reduced to a single primary breed - Records outside the cohort range or without a valid ZIP excluded What these numbers are not -------------------------- Around 80% of New York City dogs are unlicensed. Every figure describes LICENSED dogs only, and licensing is not evenly distributed across the city, so comparisons between neighborhoods carry that caveat with them. Rates are per 10,000 licensed dogs within the relevant group, never raw counts compared across groups of different sizes. "change_2008_12_to_2019_23" is the ratio of a name's rate among dogs born 2019-2023 to its rate among dogs born 2008-2012. It is left blank where fewer than 5 dogs of that name were born in the earlier window, because a ratio built on one or two animals is noise. Those names are flagged "new_name" instead where they have a real recent presence. Contact ------- https://pupcensus.com ยท hello@pupcensus.com
