American Indian and Alaska Native (AIAN) adults have long been more likely to coreside with their grandchildren under 18 than the total population (Ellis and Simmons 2014; Simmons and Dye 2003). Despite this, little recent research has examined who these coresident grandparents are. Most of the research we have comes from the 1990s or uses 2000 Census data and does not explore any within-group differences for this diverse group of grandparents. Given their high rates of grandparent coresidence, this poster and accompanying tables provide descriptive statistics of the population and several subpopulations. These statistics provide insight into the specific challenges and barriers facing AIAN grandparents living with and raising their grandchildren, and how these challenges vary based on tribal affiliation and geographic location. We also consider other sociodemographic characteristics and their association with multigenerational households to document trends within this population and to better understand the living arrangements and experiences of American Indian and Alaska Native populations, and how these trends vary based on geographic location and tribal affiliation. Data for this study come from the 2018 – 2022 5-year American Community Survey (ACS).
