Question: When did the one child policy end in china?

Disambiguated questions and answers:
context: China's one-child policy was part of a birth planning program designed to control the size of its rapidly growing population. Distinct from the family planning policies of most other countries (which focus on providing contraceptive options to help women have the number of children they want), it set a limit on the number of births parents could have, the world's most extreme example of population planning. It was introduced in 1979 (after a decade-long two-child policy), modified beginning in the mid 1980s to allow rural parents a second child if the first was a daughter, and then lasted three more decades before being eliminated at the end of 2015. The policy also allowed exceptions for some other groups, including ethnic minorities. Thus, the term "one-child policy" has been called a "misnomer", because for nearly 30 of the 36 years that it existed (1979–2015), about half of all parents in China were allowed to have a second child.

context: Beginning in 1980, the official policy granted local officials the flexibility to make exceptions and allow second children in the case of "practical difficulties" (such as cases in which the father was a disabled serviceman) or when both parents were single children, and some provinces had other exemptions worked into their policies as well. In most areas, families were allowed to apply to have a second child if their first-born was a daughter. Furthermore, families with children with disabilities have different policies and families whose first child suffers from physical disability, mental illness, or intellectual disability were allowed to have more children. However, second children were sometimes subject to birth spacing (usually 3 or 4 years). Children born in overseas countries were not counted under the policy if they did not obtain Chinese citizenship. Chinese citizens returning from abroad were allowed to have a second child. Sichuan province allowed exemptions for couples of certain backgrounds. By one estimate there were at least 22 ways in which parents could qualify for exceptions to the law towards the end of the one-child policy's existence. As of 2007, only 36% of the population were subjected to a strict one-child limit. 53% were permitted to have a second child if their first was a daughter; 9.6% of Chinese couples were permitted two children regardless of their gender; and 1.6% – mainly Tibetans – had no limit at all.
