California Health Maps uses boundaries for the 111th Congress, happening from 2009-2011 and overlapping in time with the other 2010 data used.Ģ010 California State Senate districts define the boundaries of areas represented in the CA state senate (more information at the Census website).Ģ010 California State Assembly districts define the boundaries of areas represented in the CA state assembly (more information at the Census website).Ģ010 California Counties define the boundaries of the 58 California Counties. House of Representatives (more information at the Census website). 2010 data were used.ġ11th Congressional districts define the boundaries around areas which are represented by the U.S. Spatial data are available via OSHPD at the California Open Data Portal.Ĭensus designated places are bounded areas designating cities, towns, unincorporated populations, and other 'settled concentrations of populations' (more information at the Census website). The most recent MSSA dataset (2014) was used. Each census tract in CA is assigned to a given MSSA.

We used a software zone design program called AZTool to identify aggregations of adjacent tracts and counties that optimize the three objectives: a target population of 50,000, geographic compactness, and similarity in terms of minority population, poverty, and urbanicity characteristics.Īs defined by California's Office of Statewide Health Planning and Development (OSHPD) in 2013, 'MSSAs are sub-city and sub-county geographical units used to organize and display population, demographic and physician data' ( Source). Poverty data came from the American Community Survey 2012-2016 5-year data.

We used population data from Census 2010 and Census 2010 tract geographies to construct the zones. Three demographic and socioeconomic characteristics were used to determine similarity: the percent minority population (percent of the population who are not non-Hispanic White), percent of the population with incomes below poverty, and the proportion of the population living in urban and rural areas. For the rest of the state, adjacent counties and parts of counties were combined to form zones. The minimum population for each zone is 50,000 people.Ĭounties with larger populations (more than 100,000 people) were divided into multiple zones by combining adjacent census tracts. These zones have been designed so that they have a minimum population, have similar demographic and socioeconomic characteristics, and are geographically compact (they minimize the distance between different parts of the zone).

Due to irregularities and availabilities in census tract-level cancer case and 2020 population estimate data, the next update to California Health Maps will be published in 2024.Ĭalifornia Health Maps also includes selected population sociodemographic data based on 2015-2019 American Community Survey data, SEER census tract estimates by race/origin (controlling to vintage 2019), and Census 2010. Cancer incidence rates are calculated from California Cancer Registry data and are updated regularly. It allows users to interactively map health data for California at different geographic levels: census tract aggregation zones, medical service study areas (MSSAs), census designated places, congressional districts, state senate districts, state assembly districts, and counties.Ĭalifornia Health Maps include 5-year and 10-year cancer incidence rates based on the most current data for 12 of the most common invasive cancer sites by sex and race/ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic, and non-Hispanic Asian/Pacific Islander). The California Health Maps project aims to provide data for geographies beyond the county level to better serve cancer control, public health, and policy efforts.
