Only 19 per cent of social worker positions in Jerusalem serve the Palestinians, who make up a third of the city's residents, and generally are in a much worse socio-economic state, Acri said.
The group published figures showing that 65 per cent of Palestinian families in East Jerusalem exist below the poverty line, as opposed to 31 per cent of the city's Jewish families.
Seventy-five per cent of Palestinian children in East Jerusalem live in poverty, compared with 45 per cent of the city's Jewish children, the group reported.
"Over 95,000 children in East Jerusalem live in a perpetual state of poverty," Acri said.
The office of Nir Barkat, the Israeli mayor of Jerusalem, told the AFP news agency that it had no immediate comment on Monday's report.
The definition of the "poverty line" used in the report was the same as that used by the Israeli Centre for Statistics, set at 50 per cent of the median available household income.

The poverty line in 2007 was a monthly income of $770 for a family of two and $1,400 for a family of five.
Acri said Palestinians faced discrimination in almost all sectors of life.
"Israel's policy for the past four decades has taken concrete form as discrimination in planning and construction, expropriation of land, and minimal investment in physical infrastructure and government and municipal services," the report said.
Ziad Al-Hammouri, the director of the Jerusalem Centre for Social and Economic Rights, said that the situation for Palestinians in Jerusalem is getting worse "on a daily basis".
"It's different to even compare East and West Jerusalem," he told Al Jazeera.
"Just look at the streets. In East Jerusalem, there are not even pavements.
"Economical pressure is just one of the elements used by Israelis to succeed in their plans - to get the Palestinians to leave Jerusalem and to replace them with settlers."
About 160,000 Palestinianresidents have no suitable and legal connection to the water network and 50km of main sewage lines are lacking, Acri said.
The annual budget allocation per elementary school child in East Jerusalem was $152 (577 shekels) compared with $627 (2,372 shekels) in the west of the city.
Acri also said there is a shortage of about 1,000 classrooms in East Jerusalem.
Israel has expropriated more than one-third of East Jerusalem land which was privately owned by Palestinians, on which it has built more than 50,000 homes for the Jewish population.
Virtually no permits for Palestinian housing construction have been issued for decades.
At the end of 2009, approximately 303,400 Palestinians lived in East Jerusalem, which equals 36 per cent of the city's total population of about 835,500.
The Acri report was to be published ahead of Israel's celebrations to mark the 43rd anniversary of its capture of East Jerusalem.
Israel seized and occupied the West Bank, including East Jerusalem, in 1967.
The move was met with international condemnation and the United Nations immediately declared Israel's occupation as illegal under international law.
