According to R.J. Lehmann, who analyzes financial services at the R Street Institute,  rising insurance premiums under the NFIP have driven policyholders away. A federal law enacted in 2012 led to substantial premium hikes as Congress sought to reduce the number of policyholders that received discounts.

“I do think there’s something to be said for the private insurance industry’s talent at marketing,” Lehmann said. “They are willing to spend money to market it if they had incentive to do so.”
