Response	Number of Homes*	Percentage of Total Homes Visited
Completed	187	41.6
Refused	63	14.0
No Response	190	42.3
Vacant or Inaccessible	9	2.0
Completion Response Rate†	187/(449 – 190 – 9)	75.0
Participation Rate‡	187/449	42.0
Visits Per Completed Survey§	(187 × 2) + (63 × 1) + (9 × 1) + (190 × 5)/187	7.5

^*Total number of homes visited = 449.

^†Completion response rate = Completed surveys/(Total homes accessed – No response – Other).

^‡Participation rate = Completed surveys/Total homes accessed.

^§Visits per completed survey = (Completed surveys × 2 visits) + (Refused × 1 visit) + (Other × 1 visit) + (No response × 5 visits)/Completed surveys.
