Some 500,000 Dutch households had purchasing power of more than €50,000 last year, a rise of 120,000 on 2013, the national statistics office CBS said on Wednesday.

Purchasing power is disposable income adjusted for differences in household size and composition and is also referred to as standardised income, the CBS said.

The Netherlands has some 7.7 million households and the figures show 7% have purchasing power of more than €50,000, mainly due to economic growth, the CBS said.

Some 55,000 families had purchasing power of more than €100,000 – up around 12,000 on 2013.

The CBS survey also showed that the self employed are more likely to be high earners – with 20% having purchasing power of more than €50,000. In the population at large, just 7% of workers earn such high amounts.
