What was Qatar's estimated population in the 1970s?

In the 1970s, Qatar's estimated population was just over 100,000. This population figure reflects the early stages of Qatar's development as a nation, which primarily relied on traditional industries such as pearl diving and fishing before the discovery of oil and natural gas in the 20th century. During this time, the country had not yet experienced the rapid population growth associated with the subsequent economic boom driven by energy resources. The other options significantly overestimate the population numbers for that period, as they consider the demographic shifts and increases that occurred in later decades, particularly following the oil boom in the 1980s and beyond.
