Statistical data gathering through a census is a well-developed theoretical model for modern governance and nation-building.

45. Data for this project came directly from the 1930 census ballots. In 1988, the Genealogical Society of Utah (GSU) microfilmed the extant original ballots for the 1930 Mexican population census as part of a larger genealogical and record archiving project. Copies of the microfilm, catalogued primarily by municipality and pueblos within municipalities, are available through family history centers of the Church of Jesus Christ of Latter-day Saints.

Microfilm coverage of census ballots from Sonora is fairly complete, with seventy-two percent of the population represented. Ballots for the remaining twenty-eight percent of the population in a number of municipalities (Alamos, Bacanora, Bátuc, Etchojoa, Huatabampo, Navojoa, Opodepe, Pitiquito, Sahuaripa, San Pedro de la Cueva, Santa Ana, Suaqui, Tepache, Tepupa, and Trincheras) were not microfilmed, apparently because they were missing from the ballots provided to the GSU. The aggregate census data that the National Department of Statistics published in 1934 does not report the geographical distribution of the 3,571 Chinese across Sonora's seventy-four municipalities. Assuming, however, that Chinese represent the same proportion of the population in the municipalities whose census ballots were microfilmed and in those whose ballots were not, the census ballots reviewed for this project represent seventy-two percent of the population counted as Chinese in Sonora. The reasonableness of this assumption is born out by this project's count of individuals identified as Chinese in the microfilmed ballots at 2,558, or 71.6 percent of the official total of 3,571.

The official census count identifies the Chinese population in Sonora as overwhelmingly male at 3,159 or eighty-eight percent. Quinto censo, 109. Because of their predominance in the population and the patrilineal and patriarchal character of contemporary nationality law, these men became the primary reference points of the study. Of the twelve percent of the Chinese population that was female, only a very small handful were adult women born in China. Adult women's identification as Chinese largely derived from Mexico's dependent nationality laws that, as discussed in detail below, expatriated native-born women who married foreigners. Beyond the summary data, the census ballots themselves present a rich, virtually untapped, set of data relating to the Chinese experience in Mexico. Robert Chao Romero is one of the very few other scholars who have used the 1930 Mexican population census ballots rather than the summarized data to explicate the Chinese experience in Mexico. See Romero, The Dragon in Big Lusong.

89. My review of archival files of federal cases of first instance involving Chinese in Sonora in the early twentieth century shows that the judge granted relief in virtually all cases in 1924 where individuals protested against enforcement of two 1923 state laws, the anti-miscegenation Ley 31 and Ley 27 that created Chinese ghettos. In contrast, by 1931 and with a number of different judges, the complainant prevailed in almost no case, whatever the law at issue. I have summarized my findings in a document entitled “Amparo pedido por chinos, Datos del inventario del Juzgado Quinto de Distrito, 1900–1943,” which I developed from files at the archives of the Supreme Court, Hermosillo, Sonora, Mexico.
