UCLA Energy Atlas

UCLA Energy Atlas

Data sourced from UCLA Energy Atlas. Includes building energy use by city and building type.

Data by Special Planning Area from LA County Public Health for the purposes of normalizing counts of ED visits. Data is normalized by population and includes counts of heat stress ED visits by Special Planning Area from LACDPH.
Omitted SPA 5 and 6 for all years except 2008 because the counts were too small.

Geospatial data of gentrified census tracts and proximty to high quality transit areas.
The proximity of gentrified census tracts to 2012 HQTAs was mapped. California Housing Partnership identified tracts that gentrified between 2000 and 2013, defining gentrification as socioeconomically disadvantaged neighborhoods that experienced faster changes in the following areas relative to County-level trends during the same period: 1) the percentage point increase in college educated population; 2) the percentage point increase non-Hispanic white population; 3) absolute value increase in median household income; and 4) the absolute value increase in gross rent. The gentrified census tract layer was added to a map of 2012 HQTAs within LA County.

Data describes housing affordability for selected geographies and determines the shortage or surplus of affordable housing by income group was done by CHPC for renter households for years 2014-2016.
Deeply Low Income (DLI) is defined as 0-15% of Area Median Income (AMI)
Extremely Low Income (ELI) is defined as 16-30% of AMI
Very Low Income (VLI) is defined as 31-50% of AMI
Low Income is defined as 50-80% of AMI
Moderate Income is defined as 80-100% of AMI

See https://data.lacounty.gov/Transportation/County-Employee-Average-Vehicle-Ridership-AVR-2012/b92g-vuub for more detail.

Average Vehicle Ridership (AVR) is the figure derived by dividing the employee population at a given worksite that reports to work weekdays between 6:00 a.m. and 10:00 a.m. by the number of vehicles driven by these employees commuting from home to the worksite during these hours. The AVR is calculated using a weekly averaging period. The applicable employee population is multiplied by the number of weekdays in the selected averaging period, then divided by the total number of vehicles driven by these employees to the worksite during the same period.

The survey is administered to each county department by location. The calculated AVR for each responding location was included in the data from the CSO (who received the data from the Department of Human Resources) for years 2012-2018, except 2017. An AVR of “1” means that every employee drove alone; therefore a greater AVR is a better outcome. The target AVR is set for each county department, and targets range mostly from 1.5-1.75.
For each year, a weighted average for the total AVR across county departments was calculated to account for the varied number of employees at each location and graphically presented the data.
