ADSS 1:10 Dataset Benjamin Clark 2006

ADSS 1:10 Dataset 1 in 10 sample of locations from the ADSS Database for the entire period stratified by village. Same Structure but simplified –Observation simplified to observation date –Status Observations simplified to one per year –Difficult variables remove –Increased normalization Cleaner data

Why a 1:10 Sample? Why include just 1:10 locations in each village? –Confidentiality –Helps to clean outliners Why “training” database helps users and AHPU –Expedite access to databases without losing control over publishing process –Allows users to become knowledgeable about what is available in dataset before requesting tailored datasets

Validating Sample Created and compared counts of births, deaths, in/out migrations, and household size at population and sample level to assure representativeness of sample Sample means (of above counts) are within one standard deviation of population level means Population Level and Sample Level Statistics (in process of creating) –Population pyramids of population showing similarity in age distribution –Graphs showing similarities in household size –Graphs showing similarities in mortality and fertility trends

Rules of Database Must sign data agreement to use datasets from student database Students interested in publishing from student database must: –Apply for a full custom dataset (signing a confidentiality agreement in same vein as AHPU researchers) –Will re-run analysis on custom dataset –Will work with an Agincourt researcher(s) –Will be able to publish results
