During the first two weeks of the Iranian new year (began March 20), 40,945 births were registered in the country, said Ali Akbar Mahzoon, Head of the population information office at the Organization for Civil Registration. “The provinces of Tehran, Khorasan Razavi, and Khuzestan had the highest birth rates in this period respectively,” he said, IRNA reported. “The national sex ratio at birth currently stands at 100 girls to 106 boys.” The present national population growth rate is at or near 1.4. Iran’s median age is expected to increase from 28 in 2013 to 40 by 2030, suggesting the possibility of zero population growth rate by 2050. The fertility rate is highest in Sistan-Baluchestan Province with a rate of 3.7 and lowest in Tehran with less than one birth per woman. Like in other parts of the world, urban families in Iran normally tend to have less number of children compared to their rural peers.
