The federal government recently reclassified race and ethnicity groups in an effort to better capture the diversity of the United States, but some groups feel the changes are still missing the mark. Hmong, Armenian, Black Arab and Brazilian communities in the U.S. feel that they are not accurately represented in the official numbers that their government produces. While the revisions were widely applauded, these communities say the changes have created a tension between how the federal government classifies them and how they identify themselves. Advocates are hoping revisions will be made before the next census in 2030.
