Changing census methodologies
Traditional Data Collection• PAPI• CAPIMixed Data Collection• PAPI and CAPI• Field enumeration and self-response (Internet/ telephone and CAPI)
Combined census methodology• Field enumeration and registers• Registers and sample surveys (short form register-based; long form
sample survey)• Field enumeration and rolling surveys• Registers and existing sample surveys
Fully register-based
