1. 1 1 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)hen@ssb.no Statistics Norway

2. 2 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

3. 3 The importance of good quality address data People Businesses Properties Addresses Buildings The common identifier for these units: address Three base registers in Norway

4. 4 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

5. 5 The main elements of a solution for regional statistics in Norway

6. 6 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

7. 7 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

8. 8 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

9. 9 Statistical tract Kongsvinger Oslo Address coordinates Rogaland Urban settlements R = RuralU = Urban Some examples of information linked by address

10. 10 CPR GAB Education Social security Income Labour market Housing Census Traditional Persons Families Couples House- holds Dwellings The Census 2001 data capture Persons: Registers Housing and dwellings: Census forms Families and households: Registers and forms Combined method in 2001: € 12 500 000 Registers only for 2011: € 1 250 000 (estimate)

11. 11 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

12. 12 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
