Latin America is the largest and fastest-growing geographic region of the Mormon Church outside of North America. In 2013, membership in Latin America represents almost 40 percent of the church. The growth and expansion in Latin America is a relatively recent event, occurring primarily during the last quarter of the twentieth century, and was significant enough to accelerate the internationalization of the Mormon Church. The rapid growth highlighted social challenges in the church related to race, retention, missionary work, and education. Growth is projected to continue resulting in further cultural changes in the church. Just as the growth of the church in the United Kingdom strongly determined the course of nineteenth-century Mormonism, so the expansion of the church in Latin America has made Mormonism a different church than it was fifty years ago.
