With the municipal reorganization of 1974, the North Riding of Yorkshire became North Yorkshire and most of the West Riding of Yorkshire became West Yorkshire. North Yorkshire expanded down into the northeast part of what had been the West Riding. The administrative district so formed was named the Harrogate District and included some parishes from the North Riding (including the detached part of Thirsk Rural District) within its boundaries. The remainder of Thirsk RD were placed in the Hambleton District.

The two maps were produced to different scales. A list of all the parishes is given below.
