The number of 100-year-olds in Scotland has risen to a record high of 830, according to official records.
Figures based on the 2001 census estimate that the total grew from 580 a decade ago.
Audrey Robertson, acting Registrar General for Scotland, suggested the number could continue to grow because of a baby boom in the early 1920s.
"The number of centenarians living in Scotland has been steadily rising, from 580 in 2002 to 830 in 2011, which is a growth of 43%," she said.
"Around eight out of every 10 centenarians are women. Estimates of the number of people aged 90 to 99 show relatively big increases in 2010 and 2011.
"This is partly due to births in 1920 and 1921 being much higher than in the preceding years.
"The number of births in 1920 was the highest since the introduction of national registration in 1855."
About 700 of the centenarians are women while 130 men reached the milestone, the records showed.
Despite the growth in numbers, the ratio works out at less than two centenarians for every 10,000 people.
