Experimental Design
As a first step, SERP identified program-eligible households from 100 villages in 5 selected districts (Kumuram Bheem Asifabad, Narayanpet, Mulugu, Vikarabad, Nagarkurnool). Program eligibility is defined by SERP in consultation with community-based organisations, based on marginalisation, vulnerability, and exclusion. All eligible households must be:
• Rural, located in one of 8 mandals across 5 identified districts (Kumuram Bheem Asifabad, Narayanpet, Mulugu, Vikarabad, Nagarkurnool)
• Headed or represented by a woman
• Ultra-poor, belonging to one or more of the following socially excluded categories:
• Scheduled Tribe (ST) households, including Particularly Vulnerable Tribal Groups (PVTGs): Kolams, Thotis, Gonds, Koyas, Chenchus
• Joginis — women subjected to ritualised exploitation under the now-banned Devadasi system, facing social ostracisation, economic marginalisation, and denial of entitlements
• Widows, deserted or divorced women
In addition to the above inclusion criteria, the program has the following exclusion criteria:
• Households without a female representative
• Non-rural households
• Tribal households with a government job (excluded from SERP eligibility criteria)
• Households in villages outside the 8 designated study mandals
After receiving the list of program-eligible households from SERP, we randomly sampled 3236 households to be included in a baseline survey. Once the baseline survey was completed in each district, we randomly assigned all villages within that district into treatment and control groups. As such, randomisation was stratified at the district level. In addition, we stratified the randomisation by the number of eligible households and number of PVTG households within a village (above vs below median along both dimensions).
In control villages, eligible households will not receive any TGLIP intervention for at least 24 months after the start of the evaluation period. Control villages are not informed about the programme. After the endline survey, control villages will receive the TGILP programme.
