While Colorado's population of undocumented immigrants more than quadrupled between the years 1990 and 2000, new census data analyzed by the nonprofit Pew Hispanic Center show that the
state's undocumented population has been stagnant since 2005, congruent with national trends.
The updated demographic figures have wide-ranging implications for future political debates on local economies, labor trends, public education and health care in Colorado which has some of the toughest immigration laws in the nation.
