The proportion of Cuban residents over 60 grew last year by 0.4 percent to nearly 2 million, Communist Party daily Granma said Thursday.
"Older adults" now constitute 17.8 percent of Cuba's 11.2 million inhabitants, the newspaper said, citing data from the National Statistics Office, or ONE.
In 1985, people older than 60 were 11.3 percent of the Cuban population. The ONE projects that proportion will grow to 30 percent within two decades as the number of working-age Cubans continues to decline "notably," Granma said.
Cuba's Communist government is concerned about the prospects for a smaller workforce and has responded by raising the retirement age.
Cuba's population shrank last year, a development the ONE and Latin American and Caribbean Center for Demography attribute mainly to aging and a decline in birth rates.
The island is expected to lose another 100,000 residents by 2025 and the population is on course to dip below 11 million in 2032.
