Why do some countries around the Persian gulf have rapidly growing populations?

Countries around the Persian Gulf, such as Qatar and the UAE, experience rapidly growing populations due to a combination of factors, including significant economic opportunities driven by oil and gas industries, which attract a large influx of foreign workers. Additionally, these nations often have higher birth rates compared to global averages. Government policies that encourage Immigration and investment in infrastructure further support population growth. The availability of jobs and a relatively high standard of living also make these countries appealing for both expatriates and local citizens.
