The District Level Household and Facility Survey (DLHS) was initiated in 2007 with a view to assess the utilization of services provided by government health care facilities and people’s perception about the quality of services. The DLHS-3 is the third in the series of district surveys, preceded by DLHS-1 in 1998-99 and DLHS-2 in 2002-04. DLHS-3, like other two earlier rounds, is designed to provide estimates on important indicators on maternal and child health, family planning and other reproductive health services. In addition, DLHS-3 provides information on important interventions of National Rural Health Mission (NRHM). Unlike other two rounds in which only currently married women age 15-44 years were interviewed, DLHS -3 interviewed ever-married women (age 15-49) and never married women (age 15-24).
The sample size among the districts in the country varies according to their performance in terms of Ante-Natal Care (ANC), institutional delivery, immunization, etc. and it was fixed based on information related to such indicators from DLHS-2. For low performing districts, 1500 Households (HHs), for medium performing districts, 1200 HHs and for good performing districts, 1000 HHs were fixed as sample size.
The survey used two-stage stratified random sampling in rural and three-stage stratified sampling in urban areas of each district. The information from 2001 Census was used as sampling frame for selecting primary sampling units (PSUs). In rural areas, all the villages in the district were stratified into different strata based on population /HH size, percentage of SC/ ST population, female literacy (7+), etc. The required number of villages from each state were selected with probability proportional to size (PPS). In selected primary sampling units (villages), household listing was done and required numbers of households were selected using systematic random sampling.
For larger villages (more than 300 HHs) segmentation was carried out. In case of 300 to 600 HHs, two segments of equal size were made and one was selected using PPS. For PSUs having more than 600 HHs, segments of 150 HHs were created depending on the size and then two segments were selected using PPS.
In case of urban areas, numbers of wards were selected using PPS at first stage. In a selected ward, one enumeration block from 2001 census was selected again using PPS. Procedure for segmentation, household selection, etc., was same as in the case of rural PSUs.
The uniform bilingual questionnaires, both in English and in local language, were used in DLHS-3 viz., Household, Ever Married Women (age 15-49), Unmarried Women (age 15-24), Village and Health facility questionnaires.
For the first time, population-linked facility survey has been conducted in DLHS-3. In a district, all Community Health Centres (CHCs) and District Hospital (DH) were covered. Further, all Sub-centres (SC) and Primary Health Centres (PHC) which were expected to serve the population of the selected PSU were also covered. There were separate questionnaires for SC, PHC, CHC and DH. They broadly include questions on infrastructure, human resources, supply of drugs & instruments, and performance.
DLHS-3 covered about seven lakh sample households from 612 districts of the country.
The progress of DLHS-3 is listed below:-
Expected date of completion: - Remaining State reports will be ready on or before 31st March 2010.
