SULAIMANIYAH, Iraqi Kurdistan — Political concerns among Kurds and Turkmens in Iraq may impede the country's census, set to be held by late 2020, especially in the disputed oil-rich city of Kirkuk.
Iraq's last population census in 1997 put the country's population at 16 million, excluding Iraqi Kurdistan. It was estimated there were 3 million Kurds. Those figures are now out of date, and the real population unknown.
