Building an integrated poverty measure by three poverty profiles

Abstract

On the basis of estimating three poverty profiles calculated on sample surveys data, the article presents the methods for obtaining an integrated poverty measure, which solves the model of latent structural analysis with binary classes. In such surveys as Parents and Children, Men and Women in Family, HSE Russian Longitudinal Monitoring Survey, Russian Household Budget Survey, there are questions characterizing different profiles of poverty — economic, deprivation and subjective. The last-mentioned profile presents a subjective perception of one’s position on the scale of living standards. Estimates by the three profiles measure different sides of poverty, but it is not clear how they are harmonized, and whether latent poverty is statistically reflected in them. The model of the latent structural analysis may give a positive or negative answer to this question. In case of the positive answer it is proposed to take the probability of latent poverty as an integrated poverty measure. The article provides the results of calculations for three groups of households: those of pensioners, of able-bodied persons, and mixed households consisting of pensioners and the able-bodied. On the data from the largest Rosstat survey — Statistical Survey of Income and Participation in Social Programs (VNDN) were made estimates of latent poverty for urban and rural population of Russia, for households with different number of children. It shows that latent poverty and coherence of different population groups are not contrary to the meaningful views on the phenomenon. It is found out that the understated size of the subsistence minimum (absolute poverty line) leads to lack of coherence between three estimates for households of pensioners. In this case, feeling of poverty and deprivation levels are not in line with the economic estimation of poverty.
