According to https://tradingeconomics.com/country-list/sales-tax-rate?con..., out of G20 countries, 16 have sales tax rates greater than or equal to 10%. This seems to only counts national sales tax, since it lists 5% for Canada, but about 85% of Canadians live in areas with more than 10% total sales tax.
That conflates VAT rates and sales tax rates. The two tax structures are very different, and a comparable VAT has a higher nominal rate than a sales tax, because the taxable amount is typically smaller.
