To provide statistics on the number of districts, we can calculate the total number of districts, as well as any unique characteristics or counts that might be relevant.

Let's calculate the total number of districts and any unique district names.

To convert the distance from degrees to meters, we can use the approximate conversion factor where 1 degree of latitude is approximately 111,139 meters. However, since the dataset is likely using a projected coordinate system, we should first ensure the geometries are in a suitable projection for accurate distance measurement.

Let's convert the geometries to a suitable projection (e.g., UTM) and then calculate the distance in meters.

To join all the district geometries into one, we can perform a union operation on the geometries. This will combine all the geometries into a single geometry object. Let's proceed with this operation.
