The legislative power lies in the State legislature, consisting of a house of representatives and senate, except that the people have reserved to themselves the powers of initiative and referendum.
South Dakota adopted these two methods of legislative procedure in 1898 and was the first State in the United States to do so. Petitions of but 5% of the qualified voters are sufficient to secure either of these privileges. The legislature in 1936 consisted of 45 senators and 103 representatives, all elected for terms of two years. The executive department is headed by the governor, elected for two years. The governor's veto can be overridden by a two thirds majority in each house, and does not extend to bills passed directly by the people through their use of the initiative or refer endum. The governor's judicial power is represented in his right to remit fines and grant reprieves, commutations and pardons which the courts may have imposed.
The judicial powers are vested in a supreme court, circuit courts, county courts, justices of the peace and such other courts as may be created by law for cities and incorporated towns. The supreme court has appellate jurisdiction only, and two terms, at least, must be held yearly at the seat of government. It consists of five judges chosen from districts by the qualified electors and serving terms of six years each. The State is divided into districts or circuits in each of which is a circuit court with one or more circuit judges elected for a term of four years. The number of circuits can be increased by the legislature from time to time if deemed necessary. There were in 1927 12 circuits and 21 judges. In each county is a county judge elected for a two year term.
sented 96.6% of the total population, the remainder being largely Indians, who numbered 21,833. There were only 646 negroes and but 7o Chinese. The Indians are chiefly of the Dakota (or Sioux) tribes, the largest group being the Oglala Sioux at the Pine Ridge agency, which numbered 7,628 in 1925. There were also 5,700 Sioux at the Rosebud agency, 3,00o Cheyenne River Sioux near the mouth of the Moreau river, 2,500 at the Sisseton agency and 2,000 at Yankton, beside smaller bands at the Crow Creek, Lower Brule and Flandreau agencies.
A large portion of the pioneer settlers of South Dakota were foreign-born. Since there has been little immigration since 190o, however, and the original pioneers are fast passing on by death, the percentage is rapidly decreasing. Foreign-born numbered 175,865 in 1910, 82,391 in 1920 and 65,648 in 1930. In the latter year natives of Norway numbered 13,061, Sweden 6,54o and Den mark 5,298.
The Teutonic element made up of 12,739 Germans and 9,023 Russians, chiefly Mennonites, was of similar importance. The 3,351 Canadians were the next largest foreign group.
In 1930 South Dakota averaged 9.0 inhabitants per square mile. The most densely settled portion is in the south-east where some counties average over 25 persons per square mile. East of the Missouri river towns are located every eight or ten miles along the railways and are so evenly spaced that few localities are more than 15 m. from a railroad town. South Dakota is largely an agricul tural State and its high percentage of rural population (84% in 192o) is exceeded only in North Dakota and Mississippi among the States.
There are no cities larger than Sioux Falls, which had a popu lation in 1930 of 33,362.
