Development of a joint Address and Population Registration System Workshop on the Statistical Master Plan for Slovakia Bratislava, 12-13th September 2006 Coen Hendriks (hen@ssb.no) Statistics Norway
Recomandations from the Statistical Master Plan • A standard address system and register will serve multiple purposes both administrative and statistical • An address register integrated with a common population register will improve the basis for: • running social statistical surveys • periodical censuses • running statistics from registers
The importance of good quality address data Businesses Three base registers in Norway The common identifier for these units: address People Properties Addresses Buildings
Conditions for linkage by address • A standardised system for addresses, to the smallest unit (dwelling) • For the public • Alphanumerical: streetname, housenumber, entrance, dwellingnumber • In the registers which use addresses • Alphanumerical • Numerical: municipality, streetcode, housenumber, entrance, dwellingnumber • The integration of registers: using the numerical address for linkage
The main elements of a solution for regional statistics in Norway
Some examples of why addresses are important • Statistics • Regional statistics • Population and housing census from register • Other statistics • Combining different sources by linkage • The society as a whole • Emergency • Deliveries on the doorstep • GPS i ambulance, taxi, private cars
What is a good system for addresses? • Standardisation • National address regulations • A national address guide with examples from the field • Unambigious – no room for missinterpretation • In the municipaliets • Between the municipalities • Be prepared for changes in the municipal structure • Should the region level be in charge of the address register? • Demanding type of work • Work for specialists • Routines for updating • New addresses in the register • People move • Changes of address – the residents in the CPR must also get new addresses • The need for coordination between department (regulations), the registerowners, users and the public • Involvement from the SO
Opportunities for the SO. How to benefit from a Central Population Register? • For statistical purposes • The SO must have access to information from the CPR • The SO should establish a statistical copy of the CPR • A statistical copy must • Cover the whole population in Slowakia • Well documented – so that all statisticians can use it • Be of very good quality • Personal identification number • Address • Dead or alive? Resident or emigrated? • Updated regularly (idealy on a day-to-day basis) • Contribute to the quality of the CPR • Quality check by matching and analyzing different sources
Address coordinates Urban settlements Statistical tract Rogaland R = Rural U = Urban Oslo Kongsvinger Some examples of information linked byaddress
The Census 2001 data capture Labour market Social security GAB Income Persons: Registers Education CPR Families and households: Registers and forms Families Couples House- holds Persons Dwellings Housing and dwellings: Census forms Housing Census Traditional Combined method in 2001: € 12 500 000 Registers only for 2011: € 1 250 000 (estimate)
In practise • In the SO: • Produce statistics directly from the register • Cost efficient • Hard work! • Difficult! • Support sample surveys • Draw a sample, weigh the results • Postal, self enumerating surveys: use the postal address from the CPR • The SO can combine information from other registers • At a national level: unique role/position to improve quality
Final remarks • Organisation - Who should own the address register? • Norway: • The Mapping Authority is in charge of the national address register • The Tax authority is in charge of the CPR • Finland: • The CPR is in charge of the national address register – minimalize mismatch by address • Reponsability • Who is in charge of the updating? • The SOs can push the work forward • Prepare for statistical use from day one
