The population of Colorado was 4,301,261 in 2000; in 1990 it was 3,294,394. The total population changed 30.6%. The adherent totals of the religious groups listed above (1,697,259) included 39.5% of the total population in 2000.
The population of Colorado was 5,029,196 in 2010; in 2000 it was 4,301,261. The total population changed 16.9%. The adherent totals of the religious groups listed above (1,902,282) included 37.8% of the total population in 2010.
However, the change in methodology can distort assessments on growth or decline between 2000 and 2010 for each of these groups. County-level 2000 data using the new methodology are not readily available. ASARB staff has adjusted some 2000 county-level adherent statistics to allow for a more accurate picture on growth or decline. The revised maps and charts are now available on-line at www.usreligioncensus.org for those who are interested in these trends.
