The map and linked dashboard (below ) contains visualizations of data pulled from the Los Angeles Times’ Covid-19 GitHub for “places” Los Angeles County and a research article (Yearbook of the Association of Pacific Coast Geographers – 2021 )
Map 1: Infections per 100,000 persons as of March 15, 2021 Mapped at the 350 “micro neighborhoods” level during the period of very low rates following the largest spike in infections during the winter of 2020-2021. Weekly rates at this time were both modest and consistent across the county.

Map 2: Map of COVID-19 Infection Rates consolidated into 66 regional neighborhoods because of troubling spatial autocorrelation among model residuals. Note the vast difference in infection rates from darkest blue (low) to red (high) regions on the map.
Map 3: Model Residuals Map The final model “predicted” the COVID-19 infection rate extremely well (R2 = 0.93) using housing variables (Average Household Size ** , Percent Renter**,, Percent in Group Housing) as well as Income and Ethnicity (Percent Hispanic and Percent Asian). The neighborhoods in red had higher than predicted rates and the neighborhoods in blue had lower than predicted rates. Both indicate the possibility of another lurking variable (like air pollution?) that may help identify a final cause of variation in the infection rates.

Community and Trend Analyses
The three-page dashboard below contains a basemap of cumulative cases and infection rates for most communities or neighborhoods in Los Angeles County, along with interactive graphs that permit users to view recent ‘curve’ trends by community and comparative ‘curves’ for multiple communities. A third map shows the contribution of nursing homes and residential care facilities to the overall caseloads by community.
Southern California – Residential Care/Nursing Homes
Please check out my friend Lauren He’s map of Covid-19 cases in Nursing Homes and Residential Care Facilities. It’s a very important angle on the disease that is both under-reported in the press and for which it is difficult to obtain useful data. Bonus: Lauren’s a high school senior from Austin Texas.
