Российский мониторинг экономического положения и здоровья населения НИУ ВШЭ: особенности методологии, принципы организации, исследовательские возможности
The article examines the method-ology, organizational principles, and research potential of the «Russian Longitudinal Monitoring Survey — HSE (RLMS-HSE)». It describes the sample structure, its design features, and size dynamics, including expansion and reduction of the sample. The article focuses on the formation of the pure panel part of the sample, with special emphasis on respondent attrition across the 30-year survey period. It is shown that the mechanisms of this process are not random; certain groups systematically leave the panel more actively than others. For instance, the proportion of men leaving the study is consistently higher than that of women. Another significant factor is age; the age group most "retained" in the sample con-sists of respondents who were between 31 and 45 years old in 1994. Rural residents are more likely to be among those participating in the survey for 25 years or longer. Weighting as one of the most common and accessible methods is considered as an example for correcting sample bias. Meanwhile, the analysis of sampling errors in RLMS-HSE shows that bias in representative samples of each consecutive round is minor. The article presents examples of studies using the panel component of the data along with the broad set of socio-eco-nomic indicators and demonstrate the extensive potential of RLMS-HSE, including its applications in the field if interdisciplinary research.
