The assessment is based on the extremely high authority and relevance of the primary sources provided by the U.S. Census Bureau. The official social media channels for the Census Bureau directly point to the 'America's Families and Living Arrangements' data set as the definitive source for this information. An academic study further corroborates this by explicitly citing and using data from this specific 2023 Census Bureau report. This indicates that the claim originates from the most authoritative source possible on U.S. demographics. There is no conflicting evidence among the provided sources; the majority of the sources were correctly identified as irrelevant as they deal with employment, immigration, veteran's benefits, or local county matters, not national family demographic trends. While the specific data point is not quoted directly in the provided summaries, the evidence trail points directly and consistently to a credible and authoritative origin, making the statement highly likely to be true.
