LA COVID-19 Neighborhood Maps

In order to help our community understand where cases of COVID-19 exist and where the most vulnerable populations live, we’ve created a COVID-19 case map. The data is updated daily. Map 1 shows the rate of cases per 100,000 people in cities and unincorporated neighborhoods across Los Angeles County. Map 2 shows the rate of cases in City of Los Angeles neighborhoods (where data is available). 

Hover over a city/neighborhood below to see the rate of cases per 100,00 people, the total number of cases, 1-day growth rate of cases, the total number of deaths and neighborhood characteristics include the population over 65, the percent of people without health insurance, the population living below the federal poverty line, and the rate of asthma-related ER visits per 1,000 people. 

Countywide Data

Hover over the line graphs below to see the number of reported cases, hospitalizations, and deaths by date. Note that data is cumulative – meaning that each new day includes all of the cases, hospitalizations and deaths reported for all previous days. 

Further down the page, explore cases by age group and race/ethnicity.  All data on COVID-19 is pulled directly from the LA County Department of Public Health press releases. All data is updated daily, with the exception of tests which are updated weekly. Daily information is reported as of Monday, August 03, 2020.

Cases by Age:  

The number of confirmed cases by age group*: 

0 – 4: 2669

5 – 11: 5939

12 – 17: 7543

18 – 29: 45478

30 – 49: 63741

50 – 64 : 35725

65 – 79: 14338

80 and Older: 6989

*Cases by Age and Race/Ethnicity exclude Long Beach and Pasadena. 1077 cases are currently under investigation for age; 70251 cases and 18 deaths are being investigated to determine race/ethnicity

Why are These Variables Important to Measure?

Each of the variables shown on the map above are important metrics to consider when exploring the impact COVID-19 is having on our community. The rate of cases per 100,000 people allows you to compare cases across neighborhoods and cities with differing population sizes. The one day case increase variable helps community members understand how quickly the virus is spreading. 

Older adults (defined here as 65 and over) are at more risk of contracting serious cases of COVID-19 that may require hospitalization. Understanding where older adults live throughout the county will help shed light on one of the most vulnerable populations. Because COVID-19 often spreads in the lungs, people with pre-existing conditions like asthma are also at a greater risk of developing serious cases requiring hospitalization. Data on asthma-related ER visits per 1,000 people from 2017 are shown for each neighborhood to help contextualize which communities have had higher rates of serious asthma issues in the past. 

Other highly vulnerable populations are those living without health insurance and those living with incomes below the federal poverty line, due to the high cost of potential hospitalization. According to initial reports, the cost of receiving treatment for serious cases of coronavirus that require hospitalization may reach $34,000 for those without insurance.

Data Notes: 

– The number of total cases includes deaths, represents the confirmed number of cases based on available testing, and includes cases reported by Long Beach and Pasadena Public Health Departments. Data reported in LA County DPH press releases are reported as of 8 PM from the previous day and represent the “report date” rather than the “episode date.” 

– Data on testing comes from Electronic Lab Reporting (ELR) data only and is updated as more information becomes available each week. Not all laboratories submit electronic reports. 

– Data on age distribution, total population, uninsured rates, and population living below the federal poverty line come from 2018 American Community Survey 5-year estimates. Data on asthma-related ER visits come from the CalEnviroScreen 3.0. 

Geography Notes: 

– The countywide map (Map 1) includes the 88 cities in Los Angeles County as well as unincorporated neighborhoods as defined by the Los Angeles Times Mapping LA project. 

– The city of Los Angeles map (Map 2) includes neighborhoods in the city of Los Angeles as defined by the LA Times Mapping LA project. The Department of Public Health does not specify a neighborhood for several thousand cases in the City of Los Angeles, and only cases reported by neighborhood are shown in Map 2. 

– For both maps, neighborhood boundaries provided by the LA County Department of Public Health were modified to fit NDSC city and/or neighborhood boundaries. As a result, the numbers in these maps may differ slightly from the counts shown by the Department of Public Health.
