Note that registrations may be by year of registration and not by year of occurrence. This was especially the case in the beginning of the 1980s when there were many late registrations. This explains the high number of births during 1980-1986. Before 1980, the registrations were incomplete.

===Total fertility rate ===
In 1960, Iran's [[fertility]] rate was 7.3 children per woman. In 2021, the rate had fallen to 1.7 children per woman.<ref>{{cite web | url=https://data.worldbank.org/indicator/SP.DYN.TFRT.IN?locations=IR | title=World Bank Open Data }}</ref> According to a study through the [[Australian National University]], there are both micro and macro factors affecting the fertility rate in Iran, including education, economics, and culture.<ref name="demography.cass.anu.edu.au">https://demography.cass.anu.edu.au/sites/default/files/sod/publications/working-papers/88.pdf</ref> Micro-factors can include family income levels and individual choices, while macro-factors can include the country's economy, education, and shifting cultural values. The [[Cross-sectional study|cross-sectional cohort study]] examined four provinces in [[Iran]] ([[Gilan province|Gilan]], [[Sistan and Baluchestan province|Sistan & Baluchistan]], [[West Azerbaijan province|West Azerbaijan]], and [[Yazd province|Yazd]]) and found that trends show that women in all four provinces are choosing to have fewer children compared to the women born in the earlier cohorts. The majority of women agreed with statements such as "having many children is an obstacle for the parents' interests" and "having many children creates financial pressure for the family" (among others).<ref name="demography.cass.anu.edu.au"/> Other sources also suggest that delayed marriage and a tendency to limit fertility are factors affecting the decline of TFR.<ref>{{cite journal |last1=Karamouzian |first1=Mohammad |last2=Sharifi |first2=Hamid |last3=Haghdoost |first3=Ali Akbar |title=Iran's shift in family planning policies: concerns and challenges |journal=International Journal of Health Policy and Management |date=2 September 2014 |volume=3 |issue=5 |pages=231–233 |doi=10.15171/ijhpm.2014.81 |pmid=25337596 |pmc=4204741 }}</ref> A decline in TFR can lead to population decrease, and an ageing population, which can negatively impact the country's economy.<ref>{{cite web | url=https://www.investopedia.com/articles/investing/011216/4-global-economic-issues-aging-population.asp | title=4 Global Economic Issues of an Aging Population }}</ref> In response, Iranian policymakers have attempted to limit these factors by restricting access to contraceptives and surgeries that reduce fertility.<ref>{{cite news | url=https://www.theguardian.com/world/2020/jun/15/iran-bans-vasectomies-and-contraceptives-to-improve-birth-rate | title=Iran ends provision by state of contraceptives and vasectomies | newspaper=The Guardian | date=15 June 2020 | last1=Safi | first1=Michael }}</ref>
