The sudden coup d'etat attempt in Turkey was shocking partially because coups are less frequent than they used to be.
A few decades ago, there were about 15 coup attempts or confirmed coup plots every year, according to data compiled by the Center for Systemic Peace. Today, there are still about six coups every year, or eight counting alleged coups reported by regimes that researchers say may not have actually happened.
But coup plots are far less likely to lead to attempted coups, and attempted coups are far less likely to be successful than they were a few years ago. Only about a third of plots and 40 percent of attempted coups end up being successful, according to the data.
