The state has one city with a population exceeding one million: Ciudad Juárez. Ciudad Juárez is ranked eighth most populous city in the country and Chihuahua City was ranked 16th most populous in Mexico. Chihuahua (along with Baja California) is the only state in Mexico to have two cities ranked in the top 20 most populated. El Paso and Ciudad Juárez comprise one of the largest binational metropolitan areas in the world with a combined population of 2.4 million. In fact, Ciudad Juárez is one of the fastest growing cities in the world in spite of the fact that it is "the most violent zone in the world outside of declared war zones". For instance, a few years ago the Federal Reserve Bank of Dallas published that in Ciudad Juárez "the average annual growth over the 10-year period 1990–2000 was 5.3 percent. Juárez experienced much higher population growth than the state of Chihuahua and than Mexico as a whole". Chihuahua City has one of the highest literacy rates in the country at 98%; 35% of the population is aged 14 or below, 60% 15-65, and 5% over 65. The growth rate is 2.4%. The 76.5% of the population of the state of Chihuahua live in cities which makes the state one of the most urbanized in Mexico.
