Demographic Analysis Projects

Demography plays an important role in water resources planning and development. Demographic information such as population, housing, employment, and income are important data for various water resources models and analyses. Economic Analysis Section (EAS) demography staff is involved in multiple demographic projects. The following is a list of current projects:

  • Water Plan Update
  • Every year EAS demography staff updates population numbers at Detailed Analysis Units (DAUs) levels for each of the 58 California counties for the current year and for the historical trends since 2000. We then send these updated numbers to DWR's four regional offices where they are used to calculate urban/rural water use for the Water Plan Update .

    Demographic information also plays an important role in the Water Plan's regional reports and in future scenarios. For details go to the Data & Information page.

  • Groundwater Basin Prioritization
  • Using Geographic Information System (GIS) tools, EAS demography staff calculates population numbers and the rate of growth of the population for the current and future year 2030 that are overlaying the statewide groundwater 517 basins for the Groundwater Basin Prioritazation project.

  • Disadvantaged Communities (DAC)
  • EAS demography staff determines statewide DAC at diiferent geographic levels every year using the updated Median Household Income (MHI) data from the American Community Survey (ACS) of the US Census Bureau. This determination is pursuant to Proposition 1 and Proposition 84.

  • Economically Distressed Areas (EDA)
  • EAS demography staff determines statewide EDA at diiferent geographic levels every year using the updated MHI, population, income, and unemployment data from the ACS of the US Census and from the California Employment Development Department (EDD). This determination is pursuant to Proposition 1.

  • Data Visualization using Tableau
  • EAS demography staff is woking on multiple data visualization projects using Tableau software such as Water Supply/Demand, Water Budget, and Demographic data trends.
