In 2000, the INEGI estimated that about eight million Mexican-born people, which then was equivalent to 8.7% of the population of Mexico itself, lived in the United States of America. In that year, the Mexican states sending the greatest numbers of emigrants to the United States were Jalisco (170,793), Michoacán (165,502), and Guanajuato (163,338); the total number of Mexican emigrants to the United States in 2000, both legal and illegal, was estimated at 1,569,157; the great majority of these were men.  Approximately 30% of emigrants come from rural communities.  In that same year, 260,650 emigrants returned to Mexico.  According to the Pew Hispanic Center in 2006, an estimated ten percent of all Mexican citizens lived in the United States.  The population of Mexican immigrants residing illegally in the United States fell from around seven million in 2007 to about 6.1 million in 2011.  This trajectory has been linked to the economic downturn which started in 2008 and reduced available jobs, and to the introduction of stricter immigration laws in many States.  According to the Pew Hispanic Center the total number of Mexican-born people had stagnated in 2010 and then began to fall.. How many more illegal immigrants were in the United States in 2007 than 2011?
