    Errors in Housing Unit Listing and their Effects on Survey Estimates

    In the absence of a national population or housing register, field work organizations in many countries use in-field housing unit listings to create a sampling frame for in-person household surveys. Survey designers select small geographic clusters called segments and specially trained listers are sent to the segments to record the address and/or description of every housing unit. These frames are then returned to the central office where statisticians select a sample of units for the survey. The quality of these frames is critically important for the overall survey quality. A well designed and executed sample, efforts to reduce nonresponse and measurement error, and high quality data editing and analysis cannot make up for errors of undercoverage and overcoverage on the survey frame. Previous work on housing unit frame quality has focused largely on estimating net coverage rates and identifying the types of units and segments that are vulnerable to undercoverage. This dissertation advances our understanding of the listing process, using sociological and psychological theories to derive hypotheses about lister behavior and frame coverage. Two multiple-listing datasets supporttests of these hypotheses. Chapter 1 demonstrates that two well-trained and experienced listers produce different housing unit frames in the same segments. Chapter 2 considers listing as a principal-agent interaction, but finds limited support for the ability of this perspective to explain undercoverage in traditional listing. Chapter 3 has more success explaining the mechanisms of error in dependent listing. Listers tend not to correct the errors of inclusion and exclusion on the frame they update, leading to undercoverage and overcoverage. Chapter 4 tests for bias due to the observed undercoverage, but finds little evidence that lister error would lead to substantial changes in survey estimates. Housing unit listing is a complex task that deserves more research in the survey methods literature. This work fills in some of the gaps in our understanding of the listing process, but also raises many questions. The good news for survey researchers is that the listers' errors appear to be somewhat random with respect to the household and person characteristics, at least for the variables and datasets studied in this work

    As address-based sampling becomes increasingly popular for multimode surveys, researchers continue to refine data-collection best practices. While much work has been conducted to improve efficiency within a given mode, additional research is needed on how multimode designs can be optimized across modes. Previous research has not evaluated the consequences of mode sequencing on multimode mail and phone surveys, nor has significant research been conducted to evaluate mode sequencing on a variety of indicators beyond response rates. We conducted an experiment within the Racial and Ethnic Approaches to Community Health across the U.S. Risk Factor Survey (REACH U.S.) to evaluate two multimode case-flow designs: (1) phone followed by mail (phone-first) and (2) mail followed by phone (mail-first). We compared response rates, cost, timeliness, and data quality to identify differences across case-flow design. Because surveys often differ on the rarity of the target population, we also examined whether changes in the eligibility rate altered the choice of optimal case flow. Our results suggested that, on most metrics, the mail-first design was superior to the phone-first design. Compared with phone-first, mail-first achieved a higher yield rate at a lower cost with equivalent data quality. While the phone-first design initially achieved more interviews compared to the mail-first design, over time the mail-first design surpassed it and obtained the greatest number of interviews.CC999999/Intramural CDC HHS/United States2016-07-01T00:00:00Z26120203PMC4480213692

    Since the publication of the first edition in 2004, advances in mobile devices, positioning sensors, WiFi fingerprinting, and wireless communications, among others, have paved the way for developing new and advanced location-based services (LBSs). This second edition provides up-to-date information on LBSs, including WiFi fingerprinting, mobile computing, geospatial clouds, geospatial data mining, location privacy, and location-based social networking. It also includes new chapters on application areas such as LBSs for public health, indoor navigation, and advertising. In addition, the chapter on remote sensing has been revised to address advancements

    Transportation decisions can enhance or limit community participation and employment opportunities. Historically, the lack of transportation has been consistently reported as one of the most significant barriers to community participation, particularly by rural people with disabilities. A person with a disability affecting his or her mobility in the community may have to base housing and employment choices primarily on transportation connectivity. Lack of transportation may force an individual with a disability to relocate to an area with available transportation services, and/or never consider living in a location with inadequate transportation. The 1970 amendments to the 1964 Urban Mass Transportation Act (Urban Mass Transportation Act of 1970, P.L. 91‐453) established as national policy that: …elderly and handicapped persons have the same right as other persons to utilize mass transportation facilities and services; that special efforts shall be made in the planning and design of mass transportation facilities and services so that the availability to elderly and handicapped persons of mass transportation which they can effectively utilize will be assured; and that all Federal programs offering assistance in the field of mass transportation (including the programs under this Act) should contain provisions implementing this policy. This national policy statement pre‐dated the Americans with Disabilities Act (ADA) by twenty years. Since its passage in 1990, the ADA has guided national policy toward integrated accessible public transit and changed the nature of transportation services. The Federal Transit Administration’s Elderly and Persons with Disabilities Program (section 5310) has been in place since 1975 and has been particularly important in filling gaps in accessible transportation services for seniors and people with disabilities. The Research and Training Center on Disability in Rural Communities conducted a transportation policy analysis to [1] learn more about the similarities and differences among states in their approach to, policy content of, emphasis on, and organization of transportation services planned, designed, and carried out to meet the special needs of elderly individuals and individuals with disabilities; [2] identify current practices, approaches, and innovations; and [3] serve as a resource to allow state policymakers, administrators, and advocates to learn from and build on each other’s work. We reviewed state management plans that were in place prior to the August 2005 passage of the Safe, Accountable, Flexible, Efficient Transportation Equity Act ‐ A Legacy for Users (SAFETEA‐LU, Public Law 109‐59) to establish a consistent baseline among states which can be used to measure the program’s impact and progress in achieving national goals. We framed this analysis within a post‐ADA context, assuming (as stated in the 1970 national policy) that the desired outcome of the §5310 program in this century is an integrated public transportation system accessible to all, including people with disabilities and elderly individuals
