Germany reduced its VAT last year in july by 3% and reinstated it this year. This masks inflation quite a bit. Inflation last august was 0% (rest of the year was negative). So inflation compared to 2019 is also 4% for august.

He probably meant, for a certain demographics the inflation is higher since they they have a different consumption "basket" than the average citizen.

E.g. young people are more likely to rent than owning an appartement. But the general inflation reflects only the average spending on housing. So if 50% of the population owns a home, rising rents are only reflected half as strong for the general population.

However I could not find any reliable numbers how strong the contrast for each demographic group is...
