A significant number of employees within the United States identify themselves as selfemployed,
and they are distinct from the larger group identified as private jobholders. While
socioeconomic and spatial information on these individuals is readily available in standard
datasets, such as the 2000 Decennial Census Long Form, it is possible to gain further information
on their wage earnings by using data from administrative wage records. This study takes
advantage of firm-based data from Unemployment Insurance administrative wage records linked
with the Census Bureau's household-based data in order to examine self-employed jobholders -
both as a whole and as subgroups defined according to their earned wage status - by their
demographic characteristics as well as their economic, commuting, and spatial location
outcomes. Additionally, this report evaluates whether self-employed jobholders and the defined
subgroups should be included explicitly in future labor-workforce analyses and transportation
modeling. The analyses in this report use the sample of self-employed workers who lived in Los
Angeles County, California.

Social, Economic, Spatial, and Commuting Patterns of Informal Jobholders
April 2007
Working Paper Number:
tp-2007-02
A significant number of employees within the United States can be considered "informal" or
"off-the-books" workers. These workers, who by definition do not appear in administrative wage
records, are distinct from the larger group of private jobholders who do appear in administrative
records. However, while socioeconomic and spatial information on these individuals is readily
available in standard datasets, such as the 2000 Decennial Census Long Form, it is not possible
to identify the informal workers by only using such data because of the lack of accurate, formal
wage records. This study takes advantage of firm-based data that originates in Unemployment
Insurance administrative wage records linked with the Census Bureau's household-based data in
order to examine informal jobholders by their demographic characteristics as well as their
economic, commuting, and spatial location outcomes. In addition this report evaluates whether
informal jobholders should be included explicitly in future labor-workforce analyses and
transportation modeling. The analyses in this report use the sample of workers who lived in Los
Angeles County, California.

Social, Economic, Spatial, and Commuting Patterns of Dual Jobholders
April 2007
Working Paper Number:
tp-2007-01
Individuals who hold multiple jobs have complex working lives and complex commuting
patterns. Economic and spatial information on these individuals is not readily available in
standard datasets, such as the 2000 Decennial Census Long Form, because the survey questions
were not designed to collect details on multiple jobs. This study takes advantage of firm-based
data from the Unemployment Insurance administrative wage records, linked with the Census
Bureau's household-based data, to examine multiple jobholders - and specifically a sentinel
group of dual jobholders. The study uses a sample from Los Angeles County, California and
examines the dual jobholders by their demographic characteristics as well as their economic,
commuting, and spatial location outcomes. In addition this report evaluates whether multiple
jobholders should be included explicitly in future labor-workforce analyses and transportation
modeling.

Further Evidence from Census 2000 About Earnings by Detailed Occupation for Men and Women: The Role of Race and Hispanic Origin
November 2011
Working Paper Number:
CES-11-37
A 2004 report by the author reviewed data from Census 2000 and concluded "There is a substantial gap in median earnings between men and women that is unexplained, even after controlling for work experience (to the extent it can be represented by age and presence of children), education, and occupation." This paper extends the analysis and concludes that once those characteristics are controlled for, no further explanatory power is attributable to race or Hispanic origin.

Exploring Differences in Employment between Household and Establishment Data
April 2009
Working Paper Number:
CES-09-09
Using a large data set that links individual Current Population Survey (CPS) records to employer-reported administrative data, we document substantial discrepancies in basic measures of employment status that persist even after controlling for known definitional differences between the two data sources. We hypothesize that reporting discrepancies should be most prevalent for marginal workers and marginal jobs, and find systematic associations between the incidence of reporting discrepancies and observable person and job characteristics that are consistent with this hypothesis. The paper discusses the implications of the reported findings for both micro and macro labor market analysis

A COMPARISON OF PERSON-REPORTED INDUSTRY TO EMPLOYER-REPORTED INDUSTRY
IN SURVEY AND ADMINISTRATIVE DATA
September 2013
Working Paper Number:
CES-13-47
The Census Bureau collects industry information through surveys and administrative data and creates associated public-use statistics. In this paper, we compare person-reported industry in the American Community Survey (ACS) to employer-reported industry from the Quarterly Census of Employment and Wages (QCEW) that is part of the Census Bureau's Longitudinal Employer-Household Dynamics (LEHD) program. This research provides necessary information on the use of administrative data as a supplement to survey data industry information, and the findings will be useful for anyone using industry information from either source. Our project is part of a larger effort to compare information on jobs from household survey data to employer-reported information. This research is the first to compare ACS job data to firm-based administrative data. We find an overall industry sector match rate of 75 percent, and a 61 percent match rate at the 4-digit Census Industry Code (CIC) level. Industry match rates vary by sector and by whether industry sector is classified using ACS or LEHD industry information. The educational services and health care and social assistance sectors have among the highest match rates. The management of companies and enterprises sector has the lowest match rate, using either ACS-reported or LEHD-reported sector. For individuals with imputed industry data, the industry sector match rate is only 14 percent. Our findings suggest that the industry distribution and the sample in a particular industry sector will differ depending on whether ACS or LEHD data are used.

Counting The Self-Employed From Two Perspectives: Household Vs. Business Sample Data
August 1995
Working Paper Number:
CES-95-11
This study compares the number and attributes of self-employed workers using the Characteristics of Business Owners and Current Population Survey data series. Both sources of data have been widely used in empirical studies of entrepreneurship/self-employment. Substantial and inexplicable differences were found in the two data series' estimates of the number of self-employed men and women for both reference years. In terms of individual attributes, the CBO and CPS appear to report reasonably similar profiles of self-employed individuals in terms of marital status and geographic location, and similar systematic gender differences in the industrial distributions of these individuals. However, in terms of other attributes captured by both data series, including age, the two series exhibit notable dissimilarities.

Design Comparison of LODES and ACS Commuting Data Products
October 2014
Working Paper Number:
CES-14-38
The Census Bureau produces two complementary data products, the American Community Survey (ACS) commuting and workplace data and the Longitudinal Employer-Household Dynamics (LEHD) Origin-Destination Employment Statistics (LODES), which can be used to answer questions about spatial, economic, and demographic questions relating to workplaces and home-to-work flows. The products are complementary in the sense that they measure similar activities but each has important unique characteristics that provide information that the other measure cannot. As a result of questions from data users, the Census Bureau has created this document to highlight the major design differences between these two data products. This report guides users on the relative advantages of each data product for various analyses and helps explain differences that may arise when using the products.2,3
As an overview, these two data products are sourced from different inputs, cover different populations and time periods, are subject to different sets of edits and imputations, are released under different confidentiality protection mechanisms, and are tabulated at different geographic and characteristic levels. As a general rule, the two data products should not be expected to match exactly for arbitrary queries and may differ substantially for some queries.
Within this document, we compare the two data products by the design elements that were deemed most likely to contribute to differences in tabulated data. These elements are: Collection, Coverage, Geographic and Longitudinal Scope, Job Definition and Reference Period, Job and Worker Characteristics, Location Definitions (Workplace and Residence), Completeness of Geographic Information and Edits/Imputations, Geographic Tabulation Levels, Control Totals, Confidentiality Protection and Suppression, and Related
Public-Use Data Products.
An in-depth data analysis'in aggregate or with the microdata'between the two data products will be the subject of a future technical report. The Census Bureau has begun a pilot project to integrate ACS microdata with LEHD administrative data to develop an enhanced frame of employment status, place of work, and commuting. The Census Bureau will publish quality metrics for person match rates, residence and workplace match rates, and commute distance comparisons.

A New Measure of Multiple Jobholding in the U.S. Economy
September 2020
Working Paper Number:
CES-20-26
We create a measure of multiple jobholding from the U.S. Census Bureau's Longitudinal Employer-Household Dynamics data. This new series shows that 7.8 percent of persons in the U.S. are multiple jobholders, this percentage is pro-cyclical, and has been trending upward during the past twenty years. The data also show that earnings from secondary jobs are, on average, 27.8 percent of a multiple jobholder's total quarterly earnings. Multiple jobholding occurs at all levels of earnings, with both higher- and lower-earnings multiple jobholders earning more than 25 percent of their total earnings from multiple jobs. These new statistics tell us that multiple jobholding is more important in the U.S. economy than we knew.

Assimilation and Coverage of the
Foreign-Born Population in Administrative Records
April 2015
Working Paper Number:
carra-2015-02
The U.S. Census Bureau is researching ways to incorporate administrative data in decennial census and survey operations. Critical to this work is an understanding of the coverage of the population by administrative records. Using federal and third party administrative data linked to the American Community Survey (ACS), we evaluate the extent to which administrative records provide data on foreign-born individuals in the ACS and employ multinomial logistic regression techniques to evaluate characteristics of those who are in administrative records relative to those who are not. We find that overall, administrative records provide high coverage of foreign-born individuals in our sample for whom a match can be determined. The odds of being in administrative records are found to be tied to the processes of immigrant assimilation - naturalization, higher English proficiency, educational attainment, and full-time employment are associated with greater odds of being in administrative records. These findings suggest that as immigrants adapt and integrate into U.S. society, they are more likely to be involved in government and commercial processes and programs for which we are including data. We further explore administrative records coverage for the two largest race/ethnic groups in our sample - Hispanic and non-Hispanic single-race Asian foreign born, finding again that characteristics related to assimilation are associated with administrative records coverage for both groups. However, we observe that neighborhood context impacts Hispanics and Asians differently.

Poverty Estimates for Places in the United States
September 2005
Working Paper Number:
CES-05-12
This paper first describes some historical poverty trends, overall and for demographic groups and broad locations within the U.S. from an ongoing household survey, and then presents some specific information on poverty for localities by size, from the most recent decennial census (2000). Rural poverty exceeded urban poverty in 1969 and 1979, but urban poverty in 1999 was higher than rural poverty. Non-metropolitan area poverty exceeded metropolitan area poverty in each of the four censuses, but within each of those areas, rural poverty is now less than urban poverty. Within metropolitan areas, poverty is highest for those in central cities. For urbanized areas (50,000 or more population), the poverty rate is lower as the area gets larger, with the exception of the very largest-sized areas. This higher poverty for the largest places is accounted for entirely by the higher poverty rate for the central city or cities in those urban agglomerations, as the poverty rates for the parts of the urbanized areas not in the central place continue to fall as the area itself gets larger. Some of the critical relationships affecting the poverty rate of places appear to be the location of certain types of people - female householders, non-citizens, people of color, and college graduates.
