Survey On Household Income And Wealth
The Survey on Household Income and Wealth (SHIW) is a statistical survey conducted by the Sample Surveys Division of the Banca d'Italia (the Italian central bank). The main objective of the SHIW is to study the economic behaviours of Italian households. In recent years the survey has been integrated in international research projects such as the Luxembourg Income Study and the Luxembourg Wealth Study, whose aim is to produce a comparable cross-national Data Archive on household income and wealth. Starting from 2008, the survey has also been part of a project conducted by the to produce a harmonized survey on household finances and consumption in the |
Statistical Survey
Survey methodology is "the study of survey methods". As a field of applied statistics concentrating on human-research surveys, survey methodology studies the sampling of individual units from a population and associated techniques of survey data collection, such as questionnaire construction and methods for improving the number and accuracy of responses to surveys. Survey methodology targets instruments or procedures that ask one or more questions that may or may not be answered. Researchers carry out statistical surveys with a view towards making statistical inferences about the population being studied; such inferences depend strongly on the survey questions used. Polls about public opinion, public-health surveys, market-research surveys, government surveys and censuses all exemplify quantitative research that uses survey methodology to answer questions about a population. Although censuses do not include a "sample", they do include other aspects of survey methodology, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ASCII
ASCII ( ), abbreviated from American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices. Because of technical limitations of computer systems at the time it was invented, ASCII has just 128 code points, of which only 95 are , which severely limited its scope. All modern computer systems instead use Unicode, which has millions of code points, but the first 128 of these are the same as the ASCII set. The Internet Assigned Numbers Authority (IANA) prefers the name US-ASCII for this character encoding. ASCII is one of the IEEE milestones. Overview ASCII was developed from telegraph code. Its first commercial use was as a seven-bit teleprinter code promoted by Bell data services. Work on the ASCII standard began in May 1961, with the first meeting of the American Standards Association's (ASA) (now the American National Standards I ...

Panel Data
In statistics and econometrics, panel data and longitudinal data are both multi-dimensional data involving measurements over time. Panel data is a subset of longitudinal data where observations are for the same subjects each time. Time series and cross-sectional data can be thought of as special cases of panel data that are in one dimension only (one panel member or individual for the former, one time point for the latter). A study that uses panel data is called a longitudinal study or panel study. Example In the multiple response permutation procedure (MRPP) example above, two datasets with a panel structure are shown and the objective is to test whether there's a significant difference between people in the sample data. Individual characteristics (income, age, sex) are collected for different persons and different years. In the first dataset, two persons (1, 2) are observed every year for three years (2016, 2017, 2018). In the second dataset, three persons (1, 2, 3) are obse ...

Economic Data
Economic data are data describing an actual economy, past or present. These are typically found in time-series form, that is, covering more than one time period (say the monthly unemployment rate for the last five years) or in cross-sectional data in one time period (say for consumption and income levels for sample households). Data may also be collected from surveys of for example individuals and firms or aggregated to sectors and industries of a single economy or for the international economy. A collection of such data in table form comprises a data set. Methodological economic and statistical elements of the subject include measurement, collection, analysis, and publication of data. 'Economic statistics' may also refer to a subtopic of official statistics produced by official organizations (e.g. statistical institutes, intergovernmental organizations such as United Nations, European Union or OECD, central banks, ministries, etc.). Economic data provide an empirical basis for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economy Of Italy
The economy of Italy is a highly developed social market economy. It is the third-largest national economy in the European Union, the 10th-largest in the world by nominal GDP, and the 12th-largest by GDP (PPP). Italy is a founding member of the European Union, the Eurozone, the OECD, the G7 and the G20; it is the eighth-largest exporter in the world, with $611 billion exported in 2021. Its closest trade ties are with the other countries of the European Union, with whom it conducts about 59% of its total trade. The largest trading partners, in order of market share in exports, are Germany (12.5%), France (10.3%), the United States (9%), Spain (5.2%), the United Kingdom (5.2%) and Switzerland (4.6%). In the post-World War II period, Italy saw a transformation from an agricultural based economy which had been severely affected by the consequences of the World Wars, into one of the world's most advanced nations, and a leading country in world trade and exports.

Survey Of Consumer Finances
The ''Survey of Consumer Finances'' (SCF) is a triennial statistical survey of the balance sheet, pension, income and other demographic characteristics of families in the United States; the survey also gathers information on the use of financial institutions. It is sponsored by the United States Federal Reserve Board in cooperation with the U.S. Treasury Department. Since 1992, data have been collected by the National Opinion Research Center at the University of Chicago, located in Chicago, Illinois. Data from the survey are widely used, from analysis at the Federal Reserve and other branches of government to scholarly work at the major economic research centers. Methodology Participation in the study is strictly voluntary. However, because only about 4,500 to 6,500 families are interviewed in the main study, every family selected is very important to the results. In the 2004 survey, the median interview length was about eighty minutes. However, in some particularly complicated cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Socio-Economic Panel
The ''German'' Socio-Economic Panel (SOEP [], for ''Sozio-oekonomisches Panel'') is a Longitudinal study, longitudinal panel dataset of the population in Germany. It is a household based study which started in 1984 and which reinterviews adult household members annually. Additional samples have been taken from time to time. In 2015, there will be about 14,000 households, and more than 30,000 adult persons sampled. Some of the many topics surveyed include household composition, occupation, employment, earnings, health and life satisfaction. The annual surveys are conducted by the German Institute for Economic Research (DIW Berlin) and the Kantar Group. The survey is funded by the German Federal Government and the State of Berlin via the «Bund-Länder-Kommission» (State/Federal State Commission) for Educational Planning and Research Promotion.

Panel Study Of Income Dynamics
The Panel Study of Income Dynamics (PSID) is a longitudinal panel survey of American families, conducted by the Survey Research Center at the University of Michigan. The PSID measures economic, social, and health factors over the life course of families over multiple generations. Data have been collected from the same families and their descendants since 1968. It has been claimed that it is the world’s longest running household panel survey. Background The PSID gathers data about the circumstances of the family as a whole and about each individual in the family. The greatest level of detail is gathered for the primary adult(s) heading the family. The PSID has achieved high and consistent response rates, and because of low attrition and the success in following young adults as they form their own families, the sample size has grown from 4,800 families in 1968, to 7,000 families in 2001, to 7,400 by 2005, and to more than 9,000 as of 2013. By 2003, the PSID had collected informati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Household, Income And Labour Dynamics In Australia Survey
The Household, Income and Labour Dynamics in Australia (HILDA) survey is an Australian household-based panel study which began in 2001. It has been used for examining issues such as the incidence of persistent poverty; assets and income in the transition to retirement; the correlates and impact of changes in physical and mental health; and an international comparison of wealth and happiness. The survey is widely used by Australian and international researchers in the fields of economics, social science and social policy and by the Australian Government. The HILDA survey is managed by a small team from the Melbourne Institute of Applied Economic and Social Research at the University of Melbourne and the national fieldwork is carried out by ACNielsen and Roy Morgan Research. The survey is funded by the Australian Government through the Department of Social Services. HILDA has the following key features: *It collects information about economic and subjective well-being, labour m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Household Panel Survey
The British Household Panel Survey (BHPS), carried out at the Institute for Social and Economic Research of the University of Essex, is a survey for social and economic research. A sample of British households was drawn and first interviewed in 1991. The members of these original households have since been followed and annually interviewed. The resulting data base is very popular among social scientists for quantitative analyses of social and economic change. One of the most important precursors of the BHPS is the Panel Study of Income Dynamics (PSID), established in the 1960s at the University of Michigan, Ann Arbor (US). The initial BHPS sample consisted of 10,300 individuals across Great Britain. Additional samples were recruited in Scotland and Wales in 1999 and the study was extended to Northern Ireland in 2001. As a panel survey it is a form of longitudinal study. The BHPS was funded by the Economic and Social Research Council from its inception in 1989 until 2008. Sin ...

National Accounts
National accounts or national account systems (NAS) are the implementation of complete and consistent accounting techniques for measuring the economic activity of a nation. These include detailed underlying measures that rely on double-entry accounting. By design, such accounting makes the totals on both sides of an account equal even though they each measure different characteristics, for example production and the income from it. As a method, the subject is termed national accounting or, more generally, social accounting.Nancy D. Ruggles, 1987. "social accounting," '' The New Palgrave: A Dictionary of Economics'', v. 4, pp. 377–82. Stated otherwise, national accounts as ''systems'' may be distinguished from the economic data associated with those systems. While sharing many common principles with business accounting, national accounts are based on economic concepts. One conceptual construct for representing flows of all economic transactions that take place in an econom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsimulation
Microsimulation (from microanalytic simulation or microscopic simulation) is a category of computerized analytical tools that perform highly detailed analysis of activities such as highway traffic flowing through an intersection, financial transactions, or pathogens spreading disease through a population. Microsimulation is often used to evaluate the effects of proposed interventions before they are implemented in the real world. For example, a traffic microsimulation model could be used to evaluate the effectiveness of lengthening a turn lane at an intersection, and thus help decide whether it is worth spending money on actually lengthening the lane. Introduction Microsimulation can be distinguished from other types of computer modeling in looking at the interaction of individual ''units'' such as people or vehicles. Each unit is treated as an autonomous entity and the interaction of the units is allowed vary depending on stochastic (randomized) parameters. These parameters a ...
