The population changed little over the next two centuries. The population in 1901, after the American Capture of Guam, was 9,676, with the majority located in Hagåtña and Sumay on Apra Harbor. The population increased to 18,509 in 1930. The American Naval government build roads and schools in outlying areas in order to urge the population to spend time on their ranch lands and produce more agricultural products. There were eight municipalities approved by the Naval governor in the 1920s, Hagåtña, Agat, Asan, Inarajan, Merizo, Piti, Sumay and Yona, increasing to 15 in 1939.
