The Luxembourg Income Study(LIS)
This international data project began in 1983 to standardize income data.
What is the Luxembourg Income Study (LIS)?
This type of life table identifies the age at which an individual first enters poverty.
What is a basic life table?
This term refers to individuals entering the study after age 20 with unknown earlier poverty history.
What is left censoring?
This long-term survey is known for accurately measuring welfare receipt among U.S. households.
What is the PSID (Panel Study of Income Dynamics)?
This two factors are used to determine whether a person falls below or above the poverty line.
What are age and household income?
The LIS allows comparisons between countries on these economic measures.
What are poverty, income inequality, and other demographic and economic indicators
Individuals may contribute up to this many person-years to the PSID poverty life tables.
What is 25 year?
Because individuals who have experienced poverty once are more likely to experience it again, left censoring can cause this effect on poverty estimates.
What is upward bias?
PSID respondents correctly reported about this percent of income from cash public assistance programs in 1980.
What is 92 percent?
Updating the poverty statistics each year helps prevent this type of singular occurrence from distorting long-term estimates.
What is a single economic event (like a recession)?
This is the approximate number of countries whose data are included in the LIS database.
What is over 30 countries?
This version of a life table includes factors like age and household income.
What is a multivariate life table?
To correct for left censoring, researchers apply these adjustments to age-specific poverty and welfare probabilities.
What are correction factors?
PSID interviewers ask respondents whether they received income from these three categories of benefits.
What are all public assistance programs?
If someone is included in the study from ages 20 to 24, they contribute five of these.
What are 5 person-years?
