A former politician says the States will have to look for ways to make Guernsey's workforce more efficient if the population strategy is to succeed.
The Policy Council wanted to bring in 200 extra people a year to ensure there were enough people of working age, but the proposal was defeated.
It was agreed to keep population levels at the current level of more than 60,000 people over the next 60 years.
Former deputy Peter Bougourd said the island would have to make that work.
No decision was made on how to keep the population at its current figure.
