Fieldwork response tables
The fieldwork response tables show the household and individual response outcomes (response rates) for each wave of the Innovation Panel (IP). The fieldwork procedures provides information on how fieldwork was conducted for each wave.
Using Innovation Panel response outcome data
The response tables analyses rely on sample data from the IP. There are a number of response outcome codes that were combined to identify respondents, non-respondents, and ineligible units. There are separate files for the household sample, individual sample, and individual response outcomes. The allocation of units to conditions, such as the mode experiments, are all found on the household sample file (allocation is done at the household level). The files will need to be linked to examine individual differences by allocations.
The table below presents the naming convention for the data files and variables used. In this table w_ denotes the wave of interest, and will need to be replaced with a letter to represent the wave, for example c_ for Wave 3. Note that at Wave 1, the file a_indall is used for all individuals (the ‘indall’ file is generated from the household enumeration grid and includes all individuals enumerated in respondent households); for later waves the file w_indsamp is used, as these are the individuals actually issued to field, including individuals in respondent and non-respondent households. The mixed-mode allocation b_ff_modew2 is specific to the Wave 2 experiment. The variable w_hidp is used to link household data to individual data, while pidp is used to link between individual respondent datasets. Sample identifier variables appear only in Wave 4 onwards.
Variables used for Innovation Panel response outcomes

| Individual sample | a_indall_ip w_indsamp_ip | w_ivfio | w_memorig | w_hidp pidp | |
| Individual response | w_indresp_ip | w_indmode | w_hidp pidp |
Stata code
The annotated Stata code used to calculate all of the IP7 response rates presented shows the outcome codes used for responding, non-responding, and ineligible units. This logic can also be expanded to define more categorisations (e.g. separating refusals and non-contacts). The code also shows a worked example of how IP data sets are used in combination generally.
