Living Standards Measurement Survey Albania 2012

Description

The dataset is an extended version of the public micro data file of the LSMS 2012 of Albania available at (https://www.instat.gov.al/en/figures/micro-data/, accessed 13 February 2023). Documentation of the LSMS 2012 of Albania is from the World Bank (https://microdata.worldbank.org/index.php/catalog/1970, accessed 5 November 2020). The data set is ported to R and updated with approximate survey design information derived from the data itself. The units are households and the variables are expenditures on main categories, poverty measures and structural information including weights and sample design.

Details

Absolute poverty measures use a poverty line of Lek 4891 (2002 prices). Extreme poverty measures use a poverty line where the basic nutritional needs are difficult to meet. The headcount poverty variable is an indicator for the income of the household y_i being below the (absolute or extreme) poverty line z. The poverty gap variable measures the relative distance to the poverty line: (z-y_i)/z. The poverty depth variable is the square of the poverty gap variable, i.e. [(z-y_i)/z]^2, giving more weight to the poorer among the poor and thus describing the inequality among the poor.

The survey design is a stratified clustered two stage design. The primary sampling units are enumeration zones. The strata are the crossing of prefecture and urbanicity and the allocation of the psu sample to the strata is proportional to the number of households. Within strata the psu are sampled with probability proportional to number of households. Within psu a simple random sample of 8 households was selected. The weights are calibrated to population margins. All survey design informations except the strata and the weights are approximated through the weights using assumptions on the design. Since the data set has undergone data protection measures and the survey design is approximate only, inference to the population does not yield exact results. However, the complexity of the data and of the survey design are realistic.

The size of the household is not on the original data set. However, the transformation capita <- round(0.07527689 * totcons/rcons, 0) yields the number of persons in the household.

Note

With R package survey a survey design object can be built with, e.g., svydesign(~psu + hhid , strata= ~strat, fpc= ~pi1 +pi2, weight= ~weight, data=lival, pps="brewer").
