The shortage of marriage registration books, which has hit some regions in the country, could point to a serious demographic problem that has resulted from the failure of the family planning programme.
Sri Moertiningsih Adioetomo of the University of Indonesia's Demographic Institute said that the government had been too slow to respond to changes in population trends, including an increase in the number of couples getting married at an early age.
She said shortage in the marriage registration books exposed the government's hands-off approach to demographic change, especially the rising numbers of young couples.
"We observed that uneducated people, mostly in rural areas, get married after graduating from high school," he said.
If the trend continues, Sri expected that the country would experience a population boom in the next decade.
With a higher birth-to-death ratio and improved health care, Sri said that Indonesia would see a population boom between 2020 and 2030.
The National Population and Family Planning Agency (BKKBN), meanwhile, said that the country was on the verge of an upcoming population boom, with a growth rate of 1.49 per cent per year, or an increase of 4-5 million.
"This means 10,000 babies are born every day," said BKKBN chairman Fasli Jalal as quoted by Antara news agency.
Fasli said that his agency had failed to reach its target in reducing the fertility rate as mandated by the 2010-2014 medium-term development planning, according to preliminary reports of Indonesia's demographic and health survey of 2012.
