Addresses without match with the address coordinates for Day and Night population

Erik Sommer

Statistics Denmark

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).
Challenge

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

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
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)

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
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
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

A little bit of detectives work
• We will try to investigate whether these adresses exist
• Taking the adress “Baunegårdsvej 28” as an example
Is it possible to find ”Baunegårdsvej 28” on www.borger.dk (Vis kort)?

Topic: Daytime Population

Daytime Population is based on the place, where people are having their workplace according to CVR and RAS – business register. Could also include place of study.

The daytime-population in Denmark 1.1.2007:

- 2.821.641 employed persons

- distributed at 377.601 work places

No Match – Day Time Population
• 411.670 Employed persons (14,59%)
• 37.172 Work Places (9,84%)
Address Project – room for improvement
• Examples of initiatives focusing on improvement in addresses which can be used for better placement of daytime population:
• Major institutions.
• Shopping Centers.
