The dairy barn remains an iconic image of Vermont, but the 87% decrease in active dairy farms between 1947 and 2003 means that preservation of the dairy barns has increasingly become dependent upon a commitment to maintaining a legacy rather than basic need in the agricultural economy. The Vermont Barn Census, organized by a collaboration of educational and nonprofit state and local historic preservation programs, has developed educational and administrative systems for recording the number, condition, and features of barns throughout Vermont.
