The <i>Longitudinal Small Business Survey</i> (LSBS) is a large-scale telephone survey of UK small business owners and managers, commissioned by the Department for Business, Innovation and Skills (BIS). This survey is the latest in a series of annual and biennial Small Business Surveys (SBS) dating back to 2003. From 2015, the survey methodology changed to include a longitudinal tracking element. A large sample size was recruited in Year One (2015) to establish a panel of businesses that will be re-surveyed in subsequent years. This will allow a detailed analysis of how combinations of factors affect business performance.<br> <br> The LSBS is intended to:<ul><li>improve the understanding of what drives and constrains business performance and growth by addressing evidence gaps relating to the lags between many business activities and associated performance outcomes</li><li>provide improved data on current business performance and the factors that affect this. The larger survey size will provide more reliable findings for key sub-groups of the business population and in relation to activities such as seeking finance which are only relevant to part of the sample.</li></ul>The data currently available includes a panel data file, also including the cross-sectional data and weights, for respondents from Year One (2015), Year Two (2016), Year Three (2017) and Year Four (2018).
