*5.2.1 Quantitative analysis of cost-effectiveness*

Project Records and accounts were used to ascertain field costs. An Analysis of Cost-Effectiveness was done by dividing the field costs by number of direct beneficiaries within a one-year time frame and was calculated, giving a 'cost per direct beneficiary per year' for improved hygiene [31]. Direct beneficiaries are taken to be all those within the household of a CHC Member, estimated at 4.7 people per household in Rwanda, and 4 people per household in Zimbabwe based on local census.
