Nigeria - National Cooperative Baseline Survey-2007, First round

Cooperative Baseline Survey was a national survey covering all registered cooperative societies in all 774 Local Government Areas of the 36 States of the Federation, including Federal Capital Territory (FCT). The survey was designed with the State as the reporting domain. Data were then aggregated to derive estimate at Federal Constituency (FC).
The cooperative societies were classified into primary, secondary and tertiary. From within each cluster selection were made for study. All selection were random and systematic from active societies
Sample Size:
Twenty-five (25) societies (15 - Primary, 7 - Secondary and 3 - Tertiary) were selected in each state including Federal Capital Territory (FCT), Abuja. This means that a total of Nine hundred and twenty-five (925) societies were canvassed. The sample size was robust enough to provide reasonable estimates at national and sub-national levels.


In absence of tertiary, selection was ratio 15:10 for primary and secondary.
In absence of tertiary and secondary the 25 cooperative societies were selected from the listed primary.
If less than 25 cooperative societies were registered, all co-operative societies were canvassed.
