U.S. life insurers researched more requests for individual coverage in April than they did in April 2010, and activity for older applicants kept growing.

The MIB Group Inc., Braintree, Mass., has published new life activity data in an analysis of U.S. life insurers’ use of MIB databases to check individually underwritten life applications.

Overall U.S. activity volume increased 1.1% in April.

For applicants ages 0 to 44, activity volume fell 0.8%.

Activity increased 1% for applicants ages 45 to 59, and activity jumped 8.4% for applicants ages 60 and older, possibly because many baby boomers are now in their 60s.

In March, application research activity was 0.6% higher than in March 2010.
