The educational landscape of the United States has undergone significant transformation over the past three decades, with the percentage of individuals 25 and older having earned a bachelor's degree steadily increasing since the 1990s. Nationwide, 20% of those aged at least 25 had a bachelor’s degree in 1990, while in 2021 this figure jumped to 38%. However, educational attainment varies greatly across states. Many states, such as Massachusetts, Maryland, Colorado, New Jersey, and Rhode Island, alongside 15 other states, fall above the national value of 38% in 2021. However, a total of 30 states fall beneath the national value.
