Israel passed fewer than 6% of building requests by Palestinians in the occupied West Bank in 2000-07, an Israeli anti-settlement group says.
Peace Now says 91 permits were granted from 1,624 requests, in contrast to the 18,472 homes built for Jewish settlers.
The group says the data show "clear discrimination" against Palestinians in West Bank areas under Israeli control.
Military officials accused Peace Now of distorting the figures, which were taken from official Israeli statistics.
Peace Now also said, in the case of illegal buildings, the Israeli army demolished 33% of structures erected by Palestinians and 7% of the unauthorized structures built by Jewish settlers.
