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.

NOISE INFUSION AS A CONFIDENTIALITY PROTECTION MEASURE FOR GRAPH-BASED STATISTICS
September 2014
Working Paper Number:
CES-14-30
We use the bipartite graph representation of longitudinally linked em-ployer-employee data, and the associated projections onto the employer and em-ployee nodes, respectively, to characterize the set of potential statistical summar-ies that the trusted custodian might produce. We consider noise infusion as the primary confidentiality protection method. We show that a relatively straightfor-ward extension of the dynamic noise-infusion method used in the U.S. Census Bureau's Quarterly Workforce Indicators can be adapted to provide the same confidentiality guarantees for the graph-based statistics: all inputs have been modified by a minimum percentage deviation (i.e., no actual respondent data are used) and, as the number of entities contributing to a particular statistic increases, the accuracy of that statistic approaches the unprotected value. Our method also ensures that the protected statistics will be identical in all releases based on the same inputs.

A Guide to the MEPS-IC Government List Sample Microdata
September 2011
Working Paper Number:
CES-11-27
The Medical Expenditure Panel Survey-Insurance Component (MEPS-IC) is conducted to provide nationally representative estimates on employer sponsored health insurance. MEPSIC data are collected from private sector employers, as well as state and local governments. While similar information is gathered from these two sectors, differences in the survey process exist. The goal of this paper is to provide details on the public sector including types of state and local government employers, sample design, general information on the data collected in the MEPS-IC, and additional sources of information.

The Closure Effect: Evidence from Workers Compensation Litigation
January 2010
Working Paper Number:
CES-10-01
Consideration of the "best interests" of Workers Compensation (WC) claimants often involves the assumption that those who receive benefits in a "lump-sum" behave "too myopically" with respect to labor supply. However, many attorneys argue that lump-sum settlements induce a beneficial "sense of closure." In this paper, I provide an empirical context for these ideas using a unique set of linked administrative databases owned by the State of California. Upon receipt of a court-approved lump-sum settlement, WC claimants immediately increase labor supply. No such change is found for claimants who receive a court-approved settlement in which the insurer provides benefits over time, suggesting that the method of litigation settlement is a determinant of labor supply.

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.

Using Administrative Earnings Records to Assess Wage Data Quality in the March Current Population Survey and the Survey of Income and Program Participation
November 2002
Working Paper Number:
tp-2002-22
The March Current Population Survey (CPS) and the Survey of Income and Program
Participation (SIPP) produce different aggregates and distributions of annual wages. An excess of
high wages and shortage of low wages occurs in the March CPS. SIPP shows the opposite, an
excess of low wages and shortage of high wages. Exactly-matched Detailed Earnings Records
(DER) from the Social Security Administration allow comparing March CPS and SIPP people's
wages using data independent of the surveys. Findings include the following. March CPS and
SIPP people differ little in their true wage characteristics. March CPS and SIPP represent a
worker's percentile rank better than the dollar amount of wages. Workers with one job and low
work effort have underestimated March CPS wages. March CPS has a higher level of
"underground" wages than SIPP, and increasingly so in the 1990s. March CPS has a higher level
of self-employment income "misclassified" as wages than SIPP, and increasingly so in the 1990s.
These trends may explain one-third of March CPS's 6-percentage-point increase in aggregate
wages relative to independent estimates from 1993 to 1995. Finally, the paper delineates March
CPS occupations disproportionately likely to be absent from the administrative data entirely or to
"misclassify" self-employment income as wages.

Developing Content for the
Management and Organizational Practices Survey-Hospitals (MOPS-HP)
September 2021
Working Paper Number:
CES-21-25
Nationally representative U.S. hospital data does not exist on management practices, which have been shown to be related to both clinical and financial performance using past data collected in the World Management Survey (WMS). This paper describes the U.S. Census Bureau's development of content for the Management and Organizational Practices Survey Hospitals (MOPS-HP) that is similar to data collected in the MOPS conducted for the manufacturing sector in 2010 and 2015 and the 2009 WMS. Findings from cognitive testing interviews with 18 chief nursing officers and 13 chief financial officers at 30 different hospitals across 7 states and the District of Columbia led to using industry-tested terminology, to confirming chief nursing officers as MOPS-HP respondents and their ability to provide recall data, and to eliminating questions that tested poorly. Hospital data collected in the MOPS-HP would be the first nationally representative data on management practices with queries on clinical key performance indicators, financial and hospital-wide patient care goals, addressing patient care problems, clinical team interactions and staffing, standardized clinical protocols, and incentives for medical record documentation. The MOPS-HP's purpose is not to collect COVID-19 pandemic information; however, data measuring hospital management practices prior to and during the COVID-19 pandemic are a byproduct of the survey's one-year recall period (2019 and 2020).

NEW DATA FOR DYNAMIC ANALYSIS: THE LONGITUDINAL ESTABLISHMENT AND ENTERPRISE MICRODATA (LEEM) FILE
December 1999
Working Paper Number:
CES-99-18
Until now, research on U.S. business activities over time has been hindered by the lack of accurate and comprehensive longitudinal data. The new Longitudinal Establishment and Enterprise Microdata (LEEM) are tremendously rich data that open up numerous possibilities for dynamic analyses of businesses in the U.S. economy. It is the first nationwide high-quality longitudinal database that covers the majority of employer businesses from all sectors of the economy. Due to the confidential nature of these data, the file is located at the Center for Economic Studies in the U.S. Bureau of the Census. To access the data, researchers must submit an acceptable proposal to CES and become sworn Census researchers. This paper describes the LEEM file, the variables contained on the file, and current uses of the data.
