Banks have gotten safer in more ways than one since the financial crisis.
As regulators and legislators have gone to great lengths to get banks to bolster their cash positions, the cash itself has come under less frequent assault.
That's because bank robberies have declined 35 percent since 2009, continuing a 10-year trend, according to data from the FBI and SNL Financial.
Total robberies at financial institutions—commercial banks, mutual savings banks, savings and loans, credit unions and armored carrier companies—fell to 3,961 in 2014, down from 6,062 in 2009 and 6,822 in 2004.
The decline in bank crimes is generally attributed to several factors: improving security through surveillance and other techniques, better efficiency from police in capturing those who pull jobs, and the increasing migration of bank transactions out of physical buildings and to online platforms.
"While cyberattacks represent an increasing threat to financial institutions, physical security and theft prevention remain key factors in banks' management of operational risk," SNL's Chris Vanderpool and Daniel M. Burkard said in a report on the trend.
The data provide an interesting glimpse into bank robbery trends, some of which seem intuitive and others not as much.
