This dataset is the bridge between the Survey of Income and Program Participation (SIPP) 1992 and 1993 panels and the Survey of Program Dynamics (SPD) 1998-2002 annual surveys. The data collected in the 1992 and 1993 SIPP panels provide extensive background information from which to determine the effects of welfare reform. Interviewing the same households in the SPD will provide data covering the baseline pre-reform period, the reform implementation period, and the medium-term post-reform period. The data from SPD present estimates of the economic status and activities of the population of the United States. SPD provides monthly labor force data and, in addition, supplies supplemental data on work experience, income, and noncash benefits. Comprehensive work experience information is given on the employment status, occupation, and industry of persons 15 years old and over, as well as weeks worked and hours per week worked, reasons for not working full-time, total income, and income components. Information is available not only for persons currently in the labor force but also for those who are outside the labor force. Questions cover respondents' current desire for work, their past work experience, and their intentions for job-seeking. SPD also contains data covering nine noncash income sources: food stamps, school lunch programs, employer-provided group health insurance plans, employer-provided pension plans, personal health insurance, Medicaid, Medicare, CHAMPUS or military health care, and energy assistance. Basic demographic, social, and economic characteristics are supplied for each member of the household surveyed, including age, sex, race, ethnic origin, marital status, household relationship, education, and veteran status. Limited data are provided on housing unit characteristics such as number of units in structure and tenure. (Source: downloaded from ICPSR 7/13/10)

Comprehensive population and demographic data for 15 Spd Village

Abstract (en): The 2001 SPD Cross-Sectional file provides socioeconomic data for calendar year 2000. It contains basic demographic, economic, and social characteristics data for each member of the households for 2000. The subject matter is described as follows: (1) Demographic data on age, sex, race, ethnic origin, marital status, household relationship, education attainment, and veteran status. (2) Economic data on work experience, including comprehensive work experience information on the employment status, occupation, industry, weeks worked, hours per week worked, total income, and income components for people 15 years old and older. (3) Income data covering income from jobs, net income from businesses, farm, or rent, and income from pensions, dividends, interest, and social security payments. (4) Data covering noncash income sources, such as food stamps, school lunch programs, employer-provided group health insurance plans, employer-provided pension plans, personal health insurance, Medicaid, Medicare, CHAMPUS/Tricare or military health care, and energy assistance. The weights on this file are cross-sectional, therefore they are only valid for estimates of the characteristics of the cohorts of people in 2001 who were represented by both the original and nonoriginal sample people in the SPD 2001 sample. An original sample person is a sample person who was a self or proxy respondent in Wave 1 of the SIPP 1992 or 1993 panel. A nonoriginal sample person is a sample person who became part of the sample after the SIPP Wave 1 and beyond (including the SPD samples). The SIPP 1992 and 1993 Panel samples, from which the SPD sample originated, were designed to produce only national estimates of the characteristics of interest to the user. Although this 2001 cross-sectional file includes state identifiers and is weighted to current state (as well as national) controls, deriving sub-national estimates from this 9-year-old sample that has experienced severe attrition (household and person nonresponse) and other sample loss (through death, institutionalization, etc.) as well as sample cuts dictated by budgetary constraints, results in inadequate representativeness and poor coverage in some of the smaller geographic areas. Even for the national estimates, inadequate representativeness and poor coverage occur in children of all races as well as Black adults aged 20 to 39. In addition to noninterview adjustment, Bureau of the Census attempted to further correct for these deficiencies by bringing back noninterviews from the 1997 Bridge sample and from a subset of the SIPP 1992/1993 Panels. These sample cases are included in this cross-sectional file, and will be included in the third (and final) longitudinal file, as well. The universe consists of people residing in the United States, except people living in institutions, such as prisons, and nursing homes, and entire military households, in March 2001. The universe is represented by original sample persons from the 1992 and 1993 Survey of Income and Program Participation (SIPP) panels and individuals who joined their households or group quarters later as a resident. Exceptions were: those who were subsampled out because of (1) cost constraints, (2) leaving the universe associated with the SPD Bridge, and (3) they were part of the SPD 1998 sample cut, including the SPD Bridge noninterviewed households brought back in the SPD 2000, and the SIPP noninterviewed households brought back in the SPD 2001. computer-assisted personal interview (CAPI)(1) The 2001 SPD Cross-Sectional file is minimally edited and is intended for analyses of effects of welfare reform on individuals, families and households. It can be linked to the SPD Second Longitudinal, SPD First Longitudinal, the SPD 1998, the SPD 1997 Bridge, and the 1992 and 1993 SIPP Panel files. (2) The file is a rectangular, person-level file. Household- and family-level variables are included on the record for every person in the household.

The 1999 SPD Cross-Sectional file is a minimally edited file that provides socioeconomic data for calendar year 1998. It is intended for analyses of effects of welfare reform on individuals, families and households. The file can be linked to the SPD Third Longitudinal, the SPD Second Longitudinal, the SPD First Longitudinal, the SPD 1998, the SPD 1997 Bridge and the 1992 and 1993 SIPP Panel files. The file contains basic demographic, economic, and social characteristics data for each member of the households for 1999. The subject matter is described as follows: demographic data on age, sex, race, ethnic origin, marital status, household relationship, education attainment, and veteran status. Demographic data refer to the time of the interview in 1999 for the 1998 data year. Economic data include comprehensive work experience information given on the employment status, occupation, industry, weeks worked and hours per week worked, total income, and income components for persons aged 15 and over. The data on employment refer to the preceding year. Income data cover income sources such as income from jobs, net income from businesses, farm or rent, pensions, dividends, interest, and social security payments. Data on income refer to the preceding year. Noncash benefits data cover noncash income sources such as food stamps, the school lunch program, employer-provided group health insurance plan, employer-provided pension plans, personal health insurance, Medicaid, Medicare, CHAMPUS/Tricare or military health care, and energy assistance. Most data on noncash benefits refer to the preceding year. However, some questions refer to the week before the interview.

The global switchable SPD films market is experiencing robust growth, projected to reach $65.7 million in 2025. While the exact CAGR isn't provided, considering the rapid advancements in smart glass technology and increasing demand across diverse sectors, a conservative estimate of 15% CAGR from 2025 to 2033 is reasonable. This implies significant market expansion, driven by several key factors. The automotive industry's adoption of SPD films for enhanced privacy and light control in vehicles is a major growth driver. The construction sector is also witnessing increased integration of these films in smart buildings, aiming for energy efficiency and improved aesthetics. Furthermore, the development of advanced, multi-layer SPD films offering superior performance in terms of light transmission, privacy, and durability is fueling market expansion. The growing preference for sustainable and energy-efficient building materials further contributes to market growth. However, high initial investment costs associated with the installation and maintenance of SPD films currently act as a restraint. Nevertheless, ongoing technological advancements leading to cost reduction and increased accessibility are expected to mitigate this challenge in the coming years. Segmentation analysis reveals that multi-layer SPD films are commanding a larger market share compared to single-layer films due to their superior performance. Geographically, North America and Europe are expected to remain key markets, owing to high adoption rates and well-established technological infrastructure. However, the Asia-Pacific region, particularly China and India, presents significant growth potential driven by rapid urbanization and increasing disposable incomes. The market is highly competitive, with key players like Polytronix Inc., Innoptec, and Gauzy continuously innovating to maintain their market position.

The global market for switchable PDLC and SPD films is experiencing robust growth, projected to reach a substantial size. While the provided data only states a market size of 239 million in an unspecified year (likely representing a point within the 2019-2024 historical period), we can extrapolate reasonable estimations. Assuming a moderate Compound Annual Growth Rate (CAGR) of 15% (a figure consistent with growth in related smart materials markets), and using 2025 as our base year, we can project substantial market expansion. This growth is fueled by increasing adoption in automotive applications (smart windows, privacy control), construction (dynamic glazing, energy efficiency), and other sectors such as consumer electronics and healthcare.
