Error code:   DatasetGenerationCastError
Exception:    DatasetGenerationCastError
Message:      An error occurred while generating the dataset

All the data files must have the same columns, but at some point there are 10 new columns ({'town', 'land_area_sq_mi', 'county', 'lat', 'state_name', 'tickzone_url', 'slug', 'state', 'lng', 'population'}) and 5 missing columns ({'american_dog_tick_dermacentor_variabilis', 'state_slug', 'county_slug', 'deer_tick_ixodes_scapularis', 'lone_star_tick_amblyomma_americanum'}).

This happened while the csv dataset builder was generating data using

hf://datasets/tickzone/tickzone-northeast-tick-risk/towns.csv (at revision ab44ece162ecda71cd9e1115c0d5bcd18af4adb4), ['hf://datasets/tickzone/tickzone-northeast-tick-risk@ab44ece162ecda71cd9e1115c0d5bcd18af4adb4/county-tick-species.csv', 'hf://datasets/tickzone/tickzone-northeast-tick-risk@ab44ece162ecda71cd9e1115c0d5bcd18af4adb4/towns.csv']

Please either edit the data files to have matching columns, or separate them into different configurations (see docs at https://hf.co/docs/hub/datasets-manual-configuration#multiple-configurations)

TickZone Northeast Tick Risk Dataset

Open town-level tick-risk data for all 5,688 towns across the nine states of the U.S. Census Northeast (CT, ME, MA, NH, NJ, NY, PA, RI, VT), plus per-county establishment status for the three tick species of public-health concern.

Live tool: tickzone.app, a free daily tick-risk forecast. Every town gets a 0 to 100 risk score and a green, amber or red band that updates daily. No account, no ads.

Files

towns.csv (5,688 rows): per-town tick-risk score plus the underlying inputs for each town.
county-tick-species.csv (217 rows): per-county establishment status for Ixodes scapularis (deer tick), Dermacentor variabilis (American dog tick), and Amblyomma americanum (lone star tick).

How the score is built

Each town's 0 to 100 score combines:

CDC county Lyme incidence
ESA WorldCover 10 m satellite forest cover and edge density for that town
Daily weather favorability for tick activity

Snapshot date: 2026-07-05. Full methodology: tickzone.app/methodology.
