The 2017 Longitudinal Small Business Survey is a survey of 6,619 UK small business owners and managers, commissioned by the Department for Business, Energy and Industrial Strategy (BEIS). The data are gathered via telephone interview, and the results are weighted by business size, UK nation and sector.
Weighting is used to adjust the results of a survey to make them reflect the 2017 BEIS Business Population Estimates and improve their accuracy.
SMEs with employees were oversampled in order to achieve sample sizes that allow meaningful analysis, so businesses with no employees were weighted more heavily to compensate. This is why SME employers and SME non-employers are presented separately.
Statistically significant differences are identified using a one sample t test.
Figures are rounded to the nearest whole number; percentages may not add up to 100% as a result
