The Financial Industry Regulatory Authority made live on Monday statistics regarding the "trend line" detailing the number of broker-dealers entering and leaving the profession.
FINRA CEO Robert Cook noted Thursday at an event held by the Securities Industry and Financial Markets Association the decline in the number of broker-dealers.
The FINRA Statistics page says that the data "will be updated on a regular basis."
There were 635,902 registered reps at the end of 2016, down from 643,322 in 2015, according to the data.
A total of 50,641 individuals, or 8%, left the industry in 2016 while 43,221, or 7%, were new entrants.
The net number of FINRA member firms has declined every year since 2002, when there were 5,374 firms. There were 3,835 firms in 2016.
"There has been a decline," Cook said at the event. "We have new broker-dealers coming in, but we have BDs leaving as well. That's been happening for some time as well."
