🔹 Processing Steps
Population (all ages) by fokontany in 1993 and 2018 extrapolated from the 2015 data provided via Pivot assuming a 2.8% growth rate, following INSTAT standards. This **should** correspond to the 1993 and 2018 census values and be used as a starting point for other calculations.
🔹 Usage Guide
Note that INSTAT assumes a 2.8% growth rate but our calculations find the growth rate between the 1993 and 2018 census to be 2.0%. When extrapolating to other years, you can either use the official 2.8% annual growth rate from INSTAT or the 2.0% growth rate based on the difference between the 1993-2018 census. If calculating by age class, we assume 18% of the population is under 5 and 27% is between 5-14 years old. Note that an external census conducted by Pivot in some communes of the district (see dataset “Pivot Census Data”) has found very different population values and this data should be used as a denominator in calculations with extreme caution.
