  1. Addresses without match with the address coordinates for Day and Night population Erik Sommer Statistics Denmark

  2. Day- and night-time population • Day time population tells us, where the population stays in the daytime (workplace, school etc.) • Night time population tells us, where they are staying in the nighttime (residence).

  3. Challenge We want to get the best possible match with the highest possible accuracy Our intension is to put x,y-coordinates on the addresses, where people are staying during day- and nighttime and these coordinates should be as geographical correct as possible

  4. Topic: Nighttime Population Night time population is based on the place, where people are having their residence according to the CPR–population register. The population in Denmark 1.1.2009: • 5.511.451 persons • distributed on 2.563.903 households

  5. How to place these people(1) The CPR (Central Person Register) tells us the adress, but where do we get information about the geographical position? A good place to start could be in the Danish “Public Information Server” (OIS)

  6. Data from OIS

  7. Data Distribution – addresses at www.ois.dk

  8. How to place these people(2) • Joining x,y-coordinates from OIS with addresses from CPR • … and work out to which grid net cells, the addresses should be placed

  9. Distribution Persons & Households 100 x 100 meter 1. January 2009 – Denmark (OIS)

  10. No Match – Night Time Population – 1.1.2009 • 10.237 Households – addresses (0,40%) • 32.428 Persons – inhabitants (0,59%) • 9.696 Households – addresses 1.1.2008 • 30.999 Persons – inhabitants 1.1.2008

  11. Minor difference – clarification Some addresses in one municipality (Hjørring) are without gridcell ID – however they are linked to the area 100m_no_cellid;1358(persons);683(households); 860(municipality);1. jan. 2009;Hjørring

  12. Examples on residential addresses without coordinates and with no placement in a grid cell

  13. A little bit of detectives work • We will try to investigate whether these adresses exist • Taking the adress “Baunegårdsvej 28” as an example

  14. Is it possible to find ”Baunegårdsvej 28” on www.borger.dk (Vis kort)? Adresse
