Personal loans are a popular investment for many.
The trend in the latest survey, which is based on responses from 8,500 people, shows a 6% increase in the number of people who said they used personal loans in the past month.
That is the biggest jump in the last year.
The number of borrowers who said that they used them rose 6.5% to 6,848, from 6,700 last month.
The largest increases came from borrowers in their 50s and 60s, with an increase of 9% to 1,622.
There were increases in borrowers in middle-aged and older households, with increases of 9.5%.
There were also increases among those with incomes up to $75,000.
The new data comes as mortgage interest rates continue to rise, particularly for borrowers in higher-earning categories.
Rates are currently at 2.35% for home loans and 2.6% for student loans, up from 1.7% and 1.5%, respectively, in the same month last year, according to data from Freddie Mac.
The median monthly loan payment for people in the lowest 20% of earners rose to $5,500 from $4,700 in the previous quarter, the report showed.
For those in the top 20%, the median payment dropped by $1,300.
The national median loan payment is now $15,000, which puts it behind the median for the same age group.
