General Databases GENESIS-Online about 220 statistics >NUTS3 ½ billion values,about 600.000 quarterly table retrievals
Regional database for Germany with over 90 statistics for ≤ NUTS 3, of which 20 statistics for municipalities, in total about 20 million values
In total about 400 statistics of which 2/3 are EU-wide harmonized with 5,5 million monthly visits and 760.000 downloads

Grid based data
Pros more detailed regional information
stable over time (changes of boundaries do not matter)
possibilities of matching with other layers
easy to collect
efficient and easily enlargeable
Cons higher initial effort (e.g. reviewing of addresses)
limited regional accuracy (1 pixel ≠ 1 object) in case of square shaped units
high data volumes
not applicable for regional analyses at exact parcel level (vector)
higher attention to confidentiality
