Displays the distance (km) a participants home address has moved since the previous wave. This is assuming the participant had a valid response for the current and previous waves, if either is missing the result will be coded as missing. The distance is calculated based on the latitude and longitude of the central point of the participants home postcode, and utilises the Vincentys equation to calculate geodetic distance. The first instance of the variable appearing is wave 03, showing distance moved from wave 02 – 03.
Distmov_dv displays the distance (km) a participant's home address has moved since the previous wave.
