The second federal electoral district of Zacatecas (Distrito electoral federal 02 de Zacatecas) is one of the 300 electoral districts into which Mexico is divided for elections to the federal Chamber of Deputies and one of four such districts currently operating in the state of Zacatecas.[1]
It elects one deputy to the lower house of Congress for each three-year legislative session by means of the first-past-the-post system. Votes cast in the district also count towards the calculation of proportional representation ("plurinominal") deputies elected from the second region.[2][3]
