MarketWatch reports a press release from Ancestry.com that announces:
"With nearly 13 million records, the newly available 1930 Mexico National Census (El Quinto Censo General de Poblacion y Vivienda 1930, Mexico) is the most comprehensive historical Mexican census available online(1). It is estimated that this census counted approximately 90 percent of the population, therefore for nearly 30 million Americans who can trace their families to Mexico, it provides a valuable gateway to begin researching Mexican family history, especially if family, vital or religious records are lost."
