Definition: Spartiate is the term used for Spartan citizens who had gone through their military training, were eligible for the government, and did not engage in military labor. Spartiates could be ephors and were part of the assembly; however, only those of noble birth among the Spartiates could become part of the gerousia. T. Rutherford Harley ("The Public School of Sparta," Greece & Rome, Vol. 3, No. 9 (May 1934) pp. 129-139.) says there were about 8000 Spartiates in the 5th century, 1000 by the time of Aristotle, and only 700 by 244 B.C., but there were many more non-Spartiate residents of Sparta and vicinity.
Examples:The Spartiate were at least equalled in number by the Perioikoi, and outnumbered by the Helot serfs.
