resulting FQHCs were then grouped to obtain the total number per zip code. The zip code statistics were aggregated to create study area and city-level statistics. Finally, these data were combined with population data from Esri to calculate rates.
Job-to-Worker Ratio Data Job counts by income bracket were downloaded from the U.S. Census Bureau’s Longitudinal Employer-Household Dynamics data (http://lehd.ces.census.gov/) at the census tract level based on home address of employees and again based on the address of the employer. The job counts based on the employer addresses were then divided by job counts based on the employee addresses to create the job-to-worker ratios. The Longitudinal Employer-Household Dynamics program is part of the Center for Economic Studies at the U.S. Census Bureau. It produces new, cost-effective, public-use information combining federal, state and U.S. Census Bureau data on employers and employees under the Local Employment Dynamics Partnership. Under this partnership, states agree to share data on unemployment insurance earnings, employment and wages data with the U.S. Census Bureau. The Longitudinal Employer-Household Dynamics program combines these administrative data, additional administrative data, and data from censuses and surveys. From these data, the program creates statistics on employment, earnings and job flows at detailed levels of geography and industry and for different demographic groups. In addition, the program uses these data to create partially synthetic data on workers’ residential patterns.
Licensed Child Care Data California Department of Social Services Community Care Licensing Division data were geocoded using Esri ArcGIS 10 geographic information systems software. The 2011 child care providers were grouped by zip code and combined with census 2010 population data to calculate the 2011 rate. The 2013 child care providers were grouped by zip code and combined with Esri 2012 population estimates to calculate the 2013 rate. The Community Care Licensing Division (http://www.ccld.ca.gov/) promotes the health, safety and quality of life of each person in community care through the administration of an effective collaborative regulatory enforcement system.
Los Angeles County Sheriff’s Department Data Violent crimes include aggravated assault, homicide and robbery. Violent crime rates for 2007 were calculated with 2007 Nielsen Claritas population estimates. Rates for 2011 violent crime data were calculated using census 2010 population data. See http://www. lasd.org for more on the Sheriff ’s Department.
Los Angeles Police Department Data Violent crimes include aggravated assault, homicide and robbery. However, the rates in this report do not include certain particularly sensitive crimes typically included because the data were withheld from the Advancement Project. The crimes withheld included rape, child abuse, and domestic abuse, among other less common crimes. The Los Angeles Police Department-wide rate includes only crimes reported in Los Angeles city boundaries. The violent crime rate for 2007 was calculated with Nielsen Claritas population estimates for 2007. The rate for 2011 was calculated using census 2010 population data.
