"The Anbar provincial council drew up committees covering all the areas that saw military action and civilian displacement in order to precisely determine the number of families that have had to leave their homes," deputy council head Faleh al-Essawi told Anadolu Agency.
"And the total came to 42,000," he added.
Many families, he said, had fled to the Saladin, Baghdad, Babel or Karabala provinces to escape mounting violence between government troops, armed tribesmen and armed men affiliated with the Islamic State of Iraq and Levant (ISIL).
Al-Essawi said the central government had allocated $1.8 million to support displaced families – a sum, he lamented, that would only meet some 2 percent of displaced families' needs.
"Certain ministries, meanwhile, including the oil, electricity and immigration ministries, have failed to provide urgent necessities to the province," he added.
The Iraqi army is currently carrying out a major military operation in Iraq's restive Anbar province, of which Fallujah and Ramadi are the two main cities.
According to the government, the onslaught aims to flush ISIL members out of the area.
More than 100 civilians have been killed and 530 others, including women and children, injured in Fallujah since violence erupted in the city two months ago.
