CEHTP Topic Areas


Additional information

How to find data and information on the CEHTP website

  • Data and data queries:  To find data, select from the topics listed in the tabs above. Many of the topic areas have data query tools that you can use to create your own tables, charts, and maps.  These data query results pages will also have important information about the data and data sources, including tips on how the data can or can't be used.
  • Background on environment and health topics:  Learn more about specific environmental health areas by selecting from the topics listed in the tabs above.  Explore information about the environmental hazard or health issue, including definitions, risk factors, vulnerable populations, and more.

  • Information about the data sources:  Metadata, or "data about data", is available on the metadata page and for individual topic areas where data is displayed. Metadata includes information such as where the data come from and what methods were used for calculation. 

  • Tools and services:  CEHTP also has tools and services that may be helpful for accessing and visualizing data. For example, you can use our Agricultural Pesticide Web Mapping Service, currently in demonstration format on the Environmental Health Investigations Branch site, to learn about pesticide application in a specific community. While many of our tools are currently in demonstration mode, we aim to make them and their tutorials publicly available on our website. 

  • Background information for understanding data:  Environmental health data can be complex and difficult to interpret. We provide overviews of key background concepts that may help our users to better understand and use environmental health data.

Where are the data from?

Data and results available on this website were generated using data collected and provided by other agencies.  Sometimes these data are not collected expressly for public health purposes, which can make them difficult to use.  Agencies may also lack the resources to display and disseminate their data.  One of CEHTP's main goals is to improve the usefulness and accessibility of the data for public health action.       

CEHTP is also interested in understanding these topic areas from an environmental health viewpoint.  For this reason, users may find that results generated by CEHTP may differ slightly from results generated by other governmental agencies and non-governmental organizations.  The way in which results are calculated can depend on what kind of information is of interest.  Different results can still be valid, but each may be more appropriate for answering a different question.  Explanations for how CEHTP calculated results are included for each topic area. 

CEHTP values the collaboration and contributions of our data steward partners in accessing, utilizing, and displaying their data on this website.

How to request data 

In some cases, CEHTP may have data that isn't displayed here because it is too cumbersome to display (e.g. table of rates by census tract) or because we have not had the resources to integrate into the data queries.  If you are unable to find data, are interested in more detailed data, or need assistance interpreting information on the topics on our website, CEHTP may be able to assist you or direct you to the appropriate agency. 

Please contact us at (510) 620-3038 or e-mail us.
