Sampling
Sampling Procedure
As a basis for sampling, an estimated infant mortality rate (IMR) of 45 per 1,000 live births and an underfive mortality ratio (U5MR) of 60/1,000 were used, aiming to assess IMR after three years of study, and show differences in IMR between equally sized groups in the magnitude of 15 per 1,000. This could be achieved with approximately 20% of the total population, around 50,000 people. A random sampling of villages, with probability proportional to population size in each unit, was performed, and 67 population clusters were selected with a reported population size of 51,024 inhabitants in 11,089 households.
3 follow-up rounds a year (1999)
4 follow-up rounds a year (2000 - 2011)
3 follow-up rounds a year (2012)
1 follow-up round a year (2013)
1 follow-up round a year (2015)
Demographic surveillances every 2 years (1999, 2001, ..., 2011, 2013, 2015)
At demographic surveillances, the information related to socio-economic characteristics of persons (education, occupation, marital status, religion, etc.) and of househlds (annual incomes, monthly expenditures, housing type, used water source, hygiene condition, etc.) are collected;
At follow-up rounds individual vital events (birth; death; migration; sickness; marital status changes; pregnancy; etc.) and household events (enter to DSS; getting out, close; split; etc.) are noticed.
