Two provinces hold 44% of Ecuador’s people: Guayas (4.39 million) and Pichincha (3.09 million) together account for about 7.5 million of the country’s 16,938,986 residents counted in the 2022 census.
Ecuador is divided into 24 provinces, from coastal Guayas to the sparsely settled Amazon and the Galápagos Islands. This post ranks all 24 by population and looks at what the numbers show.

What stands out
The top three hold over half the country. Guayas, Pichincha and Manabí total about 9.07 million people, or 54% of Ecuador. Guayas alone is 26% and Pichincha 18%, anchored by the two largest cities, Guayaquil and Quito.
Los Ríos and Azuay close out the next tier. Los Ríos (898,652) edges past Azuay (801,609), home to Cuenca, to take fourth place; El Oro (714,592) follows.
Most Andean provinces cluster near 470,000. Chimborazo, Cotopaxi and Imbabura are within 2,100 people of each other (471,933, 470,210 and 469,879), and Loja is only slightly above at 485,421.
The Amazon is big but thinly populated. The six Amazon provinces (Sucumbíos, Morona Santiago, Orellana, Napo, Pastaza and Zamora Chinchipe) cover about 42% of the national territory but hold roughly 5.5% of the population, about 928,000 people combined. Pichincha has about 319 people per km²; Pastaza has about 4.
