Private household income distribution by income groups, 2005

Since 1946, the Central Bureau of Statistics has held regularly

research on regional income distribution.These studies are
mainly based on registers from the Ministry of Finance (the tax registers) and the Dutch municipalities (de
population registers = GBA).
The final results from the Regional

Income research (RIO) is based on a sample of more than 1.9

million households.

Income distributions of persons or households, by country, province,

COROP area, metropolitan agglomeration, urban region and municipality.

Data available from:
2005

These renewed figures from the 2005 RIO relate to 'provisional

figures.

For RIO 2005, a new production run of the

income production system took place with improved input data from the

tax registers of 2005.

With this improved input data, the number of data to be imputed on micro

level from previous research years (2004 and 2003) substantially less

this improves the quality of output.
It is now apparent from the

plausibility contoles that in the numbers and amounts small

differences are found in relation to the previous production run

from the beginning of this year, we are forced to have the existing RIO 2005

output to be revised.

The reference date is 1 January 2006;
the data relate to the

research year 2005.

Frequency:
one-off

Because the municipal division changes annually, the results are

published from the RIO for each individual research year;
merging

or division of municipalities will result in all information related

to income in a newly formed or split municipality

can change so that comparability over time is not possible.
