LEAD classification	Higher density urban	Lower density urban	Suburban/small town	Rural	Undesignated
	17,143 (23.6)	25,715 (35.5)	11,783 (16.2)	17,723 (24.4)	174 (0.2)	72,539

Undesignated census tracts are those that lack an original RUCA designation. The LEAD classification has fewer undesignated tracts because of the differing land area criteria for urbanized areas and urban clusters.
