§ Sir T. Dugdale
No precise information is available about the area of agricultural land in Glamorgan that has been taken for non-agricultural purposes during the periods mentioned. According to the annual agricultural returns, however, the total acreage of crops and grass, and rough grazings in sole occupation in the county declined by 2,467 acres in the 12 months ended 4th June, 1952. The decreases in the two year and five year periods ending on that date were 6,051 and 10,249 acres, respectively. These figures take account of any land restored to agricultural use, for example by Service Departments, and are subject to some error.
