The vast majority of people in Qatar (and in every Arab monarchy, and a significant portion of every Arab country) are not citizens, they're guest workers. Most of these guest workers are domestic labor.
Sorry, to be clearer, it is universal for Qatari citizens.
"In early 2017, Qatar's total population was 2.6 million: 313,000 Qatari citizens and 2.3 million expatriates."
