Table 1 Summary information on population survey data employed in the study
Health service utilization indicator | Household survey | Year | When the survey was conducted | Sampling strategies |
|---|---|---|---|---|
Use of curative services by level of care and stratified by socio-economic status | Living Condition and Monitoring surveys (LCMS) | 2006 | January–December 2006 | Stratified two-stage sampling technique: In the first stage, the primary units or enumeration areas (EAs) were drawn to probability proportional to the number of households counted in the EA (for a total of approximately 1000 EAs). In the second stage, households were drawn in equal probability in each of the enumeration areas (for a total of approximately 20,000 households). |
2010 | January–April 2010 | |||
Use of institutional delivery by level of care and stratified by socio-economic status | Demographic and Health Survey (DHS) | 2007 | April – October 2007 | Stratified two-stage sampling technique: In the first stage, 320 EAs were selected with probability proportional to the SEA size. An EA is a convenient geographical area with an average size of 130 households or 600 people. In the second stage, households were drawn with equal probability in each EA (for a total of approximately 8000 households). |
Use of curative services and institutional deliveries by level of care and stratified by socio-economic status | Zambia Household Health Expenditure and Utilization Survey (ZHHEUS) | 2014 | January to April, 2014 | A two-stage stratified cluster sample in the first stage, 320 EAs were selected within each stratum using the probability proportional to estimated size procedure. During the second stage, 20 households were selected from each EA using the systematic random sampling method. A total of 14,000 households were sampled and interviewed with replacements. |
