Previously, agencies accredited by the Social Development Network (SDN) were not allowed to hold events for people of a particular age group or religion, because that might appear discriminatory.
But demand from singles for dating events aimed at specific age groups or faiths prompted the Ministry of Social and Family Development to change its guidelines some time in the middle of last year.
The number of single Singaporeans above 40 years old is on the rise, and they are getting new help to find love.
Dating agencies have begun holding more mass match-making events, such as speed-dating, tailored especially for older singles since they were given the green light to do this.
They found it awkward to attend large-group events with participants mostly in their 20s or 30s.
That was an increase of more than 60 per cent from 113,000 in 2000.
Love Express has also seen 20 per cent growth in this group since 2010.
In the past, most older singles could turn to the agencies to find them a match only on exclusive one-on-one dates.
"Agencies also told us that targeted events would be more effective," a spokesman said.
The Sunday Times understands that agencies must still cap the number of such targeted events to no more than a fifth of the total number of get-togethers they hold.
Interest in events for the over-40s has been strong, said agencies.Latest available figures show there were about 184,000 singles aged 40 and above in 2010.
