Paper Data Coding Sheets for 10/66 Population-based Studies

In order to save money on photocopying and printing, we have prepared brief data coding sheets for each interview. Each interviewer will then need only one copy of the full interview, and codes the responses onto the much briefer data coding sheets instead.
