JMP Methodology - SummaryJMP Methodology - Summary Primarily based on user data derived from
household surveys and censuses rather than data reported by governments
Adjustments made to full historical series to ensure comparability over time and between countries
Use linear regression to extrapolate and interpolate reference years instead of using the latest household survey data
