Methodology
The Intuit QuickBooks Small Business Index creates aggregated data outputs from a sample of anonymized QuickBooks Online small business payroll customer records which are calibrated using statistical methods to create modeled results which better reflect the general population of small businesses in each country, as represented by published official statistics. Statistical adjustment ensures the Index truly reflects employment and job vacancy changes rather than trends in the QuickBooks customer base.

Rounded values
Total and monthly changes in employment and job vacancies have been rounded to the nearest hundred. Monthly changes and growth rates are calculated before total employment or job vacancy values are rounded. Rates have been rounded to the nearest hundredth.
Seasonal adjustments
The Index’s data insights are seasonally adjusted to limit the effect of seasonal patterns in employment and hiring throughout the year, which lead to regular fluctuations in workforce growth and contraction.
Employment growth formula
Employment growth(t) = [Employment(t)-Employment(t-1)]/[0.5*Employment(t)+0.5*Employment(t-1)]
*Employment levels
The Index produces a monthly prediction of employment growth rates by country, region, and sector. In order to translate these growth rates into the number of jobs/vacancies gained or lost, the growth rates are multiplied by the prior month’s predicted employment levels, except during the months when official statistics are published. During those months, the latest official employment levels that have been reported are used in the calculation instead of the Index’s prior month’s predicted employment levels. As a result, the Index’s predicted total employment levels may at times differ from the predicted growth rates. Official statistics are published at different frequencies depending on the country ranging from monthly to quarterly.
Time series
The Index uses data going back to January 2015 in the US and Canada and to January 2018 in the UK. Published at the earliest opportunity every month, the Index shows the number of people employed by small businesses (in the US and Canada) or the number of job vacancies at small businesses (in the UK) in the previous month and how that number has changed since the month before. The Index helps to eliminate almost all of the time lags in official statistics by providing estimated projections of what those statistics will ultimately show when they are published.
Sample sizes
The total sample across all three countries is around 424,000 small businesses. The US sample is almost 333,000 small businesses. The Canadian sample is almost 66,000 small businesses. The UK sample is almost 25,000 small businesses. The minimum sample sizes for regions or sectors to be included in the Index are 1,000 small businesses in the US, 800 small businesses in Canada, and 200 small businesses in the UK.
Target populations
In the US and UK, the Index targets the populations of small businesses with one to nine employees. In Canada, the target population is small businesses with one to 19 employees. The differences ensure the Index’s data insights are consistent with official statistics in each country, which are used for benchmarking during the calibration process. Timely data insights for these populations of small businesses are particularly valuable since most datasets fail to cover this portion of the economy well. Please note: Unlike in the US and Canada, the UK Index uses job vacancy data for calibration rather than employment data because official employment statistics are not currently available for small businesses on a monthly basis.
