Random Household Survey

Sociodig uses a sampling strategy typically based on 5 to 10 household clusters. We lay a grid over a Google Map image of the target region and then make a random, systematic selection of the desired number of clusters. Our experienced surveyors then visit the determined number of households closest to the selected GPS points and using Google Nexus tablets with built-in GPS chips, they apply the survey instrument and record the actual GPS points for validation.

Health

Sociodig conducts health surveys using Charder Stadiometers and iSnow digital scales, and ergonomic, lock-pin body measuring tapes. To assure accurate recording, two-person survey teams record measurements both manually and with photos of the actual measurement reading.

Frequency listing is a statistically robust survey method for identifying competent low-level community leaders (called notab) and/or informants.

Person on the Street

When appropriate, Sociodig maximizes the number of surveys while minimizing costs by doing surveys in popular markets and bus stations. Teams of surveyors are sent to a specific number of markets and/or bus stations where they randomize the selection of respondents by interviewing every nth person at specified intervals throughout the day and early evening. The same techniques are used for street and market vendor surveyors.
