In an effort to allay any fears between the immigrant community and federal authorities, officials with the 2010 Census met with consuls of several Latin American countries to ask for support in their communities to spread the word about the importance of being counted.

“It is vital that every person living in the United States takes part to assure accurate representation and funding for vital services”, said Marycarmen Moran, promoter of the 2010 Census, adding that the consuls agreed to do all they can to make the census a success.

Those present included, of course, representatives of the Mexican government.
