Women in Iran will have limited access to contraceptives and may be forced to become mothers to get jobs if new laws are approved.

Iranian authorities have drafted two bills aimed at boosting the population. One bans voluntary sterilization and the advertising of birth control. The other makes it harder for women to divorce and instructs workplaces to prioritise men, and women with children for certain jobs.

It comes after Supreme Leader Ayatollah Ali Khamenei issued a decree last year calling for Iran’s population to double to more than 150 million within 50 years.

The bid was slammed last week by human rights organisation Amnesty International, which warned it could reduce women to ‘baby-making machines’. But Iran is not the only country seeking to boost population figures. Singapore’s government offers parents cash gifts of up to $8,000 (£3,900) for new children to help with childrearing costs. The country’s total fertility rate ranks as the lowest worldwide, with just 0.8 children born per woman as of 2014.

Meanwhile, the global population is growing.

If current fertility rates continue, it is estimated that the human race will grow from 7.1 billion to over 11 billion by 2050.
