Americans are slightly more optimistic about their own financial situations than they were a couple of months ago, a bimonthly survey finds.

Country Insurance & Financial Services, Bloomington, Ill., reports its Financial Security Index rose to 69.9 in August, up 0.6 of a point from June and 2.1 points since April.

Younger age groups were particularly likely to rate their overall financial security positively in August than they were in June, Country reports.

Overall, 50% of the nation’s adults rated their financial security as good or excellent this period, a 4% increase since June. The strongest upsurges came from Americans ages 18-29 and 30-39, where there were increases of 6% and 4%, respectively, in the combined good and excellent ratings.

Sentiment among 18-29 year olds rose despite a drop in the number who said they were able to set aside money to save or invest from 55% to 47%.

Those who were certain they could pay all their debts on time rose from 80% in June to 82% in August, while 68% were confident their family could live comfortably if they died or were disabled, up from 64% .

The Country Index is based on a national telephone survey by Rasmussen Reports L.L.C., Chicago, of at least 3,000 Americans.
