As Andrea Weigl of the Raleigh News & Observer writes:

Here are the details: Between 2007 and 2012, the number of farmers selling directly to consumers increased 5.5 percent, while the value of sales declined by 1 percent. (These sales include transactions at farmers markets, roadside stands, pick-your-own farms and community-supported agriculture subscriptions.) For a little historical context, between 2002 and 2007, the number of farmers selling directly to consumers increased 17 percent and the value of sales increased 32 percent.

In other words, today we have more farmers splitting the same pot of money.
