Concerns regarding how the use of proxy respondents within the Labour Force Survey may affect the quality of official statistics on trade union membership data is not new. However, less attention has been given to interview mode. The analysis reveals that the mode through which an interview is conducted appears to be just as important as the more commonly cited issue of proxy response. Rates of trade union membership and presence are estimated to be higher when derived from telephone as opposed to face to face interviews.
