- \( \boldsymbol{n}=\frac{\mathbf{4}\left(\boldsymbol{r}\right)\left(\mathbf{1}-\boldsymbol{r}\right)\left(\boldsymbol{f}\right)\left(\mathbf{1}.\mathbf{1}\right)}{\left(\mathbf{0.12}{\boldsymbol{r}}^{\mathbf{2}}\right)\left(\boldsymbol{p}\right)\left({\boldsymbol{n}}_{\boldsymbol{h}}\right)} \)
- where:r= predicted coverage
- f = design effect = 1.5
- p= population proportion of target group (under 5 years and under 2000 g)
- nh= household size
