2. We support the use of European griddata
We support the use of European griddata and will continue to deliver night and day time population on 1x1 km grid for public presentation and analysis.
We are member of the European Grid Club
We have several years of expericence in delivering social statistics on household level. We have difficulties in handling business statistics on grids.

5. Social statistics - reflections
It’s not so complicated to handle data
protection and confidentiality issues in reference
to Social statistics with demographic data
about persons, families and households.
We have used households as our primary unit
and deliver data on clusters with a minimum of
20 households. Focus today is on how to create miniclusters with a minimum of 5 household to be used as building blocks in order for us to optimize clusters by the use of registerdata.

8. Business statistics - reflections
It’s more complicated with dataprotection and confidentiality issues in reference to the use of
Business statistics using workplaces as unit.
In Denmark values must be suppressed if they are based on fewer than three dataunits. And in top of that we don’t release data if a company or workplace is a dominating unit.
This makes it quite difficult to release daytime population as griddata. Solution to this sofar: intervalgroups o.k. for presentation purposes.

10. Website access and demodata
Grids and geo-statistics are of great value to the user and it’s important that we provide access to data both on national and european level.
Free access to griddata – webdata, website
with viewing facilites and download access to griddata is essential even when you have to pay later for value added services.
