contact: Contact Rates

In leeper/responserates: AAPOR Survey Response Rates

Description

AAPOR contact rate formulae

Usage

con1(i = 0, p = 0, r = 0, nc = 0, o = 0, uh = 0, uo = 0)

con2(i = 0, p = 0, r = 0, nc = 0, o = 0, uh = 0, uo = 0, e = 1)

con3(i = 0, p = 0, r = 0, nc = 0, o = 0)

Arguments

i	The total number of completed interviews.
p	The total number of partial interviews.
r	The total number of refusals.
nc	The total number of non-contacts.
o	The total number of “other” units.
uh	The total number of unknown if occupied (housing) units.
uo	The total number of other unknowns.
e	Optionally, the (estimated) proportion of units of unknown eligibility (uh anduo) that are eligible. Otherwise assumed to be 1 (all eligible).

Details

Contact rates measure the number of contacted units (including refusals and others) out of the total units sampled. The denominator for each rate varies. Here are the definitions of each response rate, according to AAPOR's “Standard Definitions”:

• Contact Rate 1 (CON1) assumes that all cases of indeterminate eligibility are actually eligible.

• Contact Rate 2 (CON2) includes in the base only the estimated eligible cases among the undetermined cases.

• Contact Rate 3 (CON3) includes in the base only known eligible cases.

One possible calculation of e suggested by the Standard Definition's calculator is the number of eligible e = \frac{i + p + r + nc + o}{i + p + r + nc + o + uo}. The default used here, however, is the more conservative value of 1.

Value

A numeric value indicating the contact rate.
