The California Pesticide Use Data Explorer was developed for Californians for Pesticide Reform by the Open Spatial Lab at the University of Chicago Data Science Institute. This publicly-accessible data tool aims to make pesticide data accessible and stable online for Californians for Pesticide Reform, statewide coalition partners, researchers, policy and decision makers, and community residents.
Pesticide Use and Demography Map View
This data view shows a map of pesticide use reporting data and
demographic data at the census tract or zip code scale. The
colors on this map represent the pounds of pesticide used in
each Area and various demographic characteristics from the US
Census American Community Survey. The color scale in the
legend show the ranges of the values based on quantile breaks
(quintile).
To change the scale from census tracts or zip codes, or change
the demographic data displayed, click the layer icon on the
legend on the bottom left of the map.
To change the date range displayed, change the start date and
end date drop downs above.
To filter the data for particular active ingredient types,
classes, or commodities, click the "Additional Filters" button
for additional options.
Your current filters are display on the right, along with a
description of data sources.
Below this map, there is a table of data at both the census
tract and zip code scale.
California’s Pesticide Use Reporting (PUR) program has collected data on California’s agriculture and many non-agriculture pesticide uses across the state since 1970 through present day. Managed and collected by California’s Department of Pesticide Regulation, PUR data is refreshed about once per year. More information is available from [CA DPR](https://www.cdpr.ca.gov/docs/pur/purmain.htm).
This interactive data explorer enables users to filter or summarize publicly available California PUR data based on the following parameters.
PUR data was accessed in Fall 2023. Data from 2010 to 2021 (the most recent data year) are available in this tool.
Spatial data enables users to query data based on the following areas, or spatial units:
Census Administrative Boundaries: ACS 2021 and 2020 boundaries, via census.gov
Community and demographic data allows users to better understand the impact of pesticide use on different populations locally and across the state. Demographic data available to filter, map, and explore include:
Census Demographic Data: ACS 2021 5-year estimates, via Social Explorer
