Well there are only a few main groups, and if we generally expect that some will respond faster than others, I'd say two or three going up would be quite indicative of general inflation. It seems like food, energy, and commodities (less food and energy) have gone up at different rates. The only major group that's been relatively stable (still about 4%) is services, and it seems likely that it's because many of them have been made illegal/unattractive for many recent months. https://www.bls.gov/news.release/pdf/cpi.pdf https://www.bls.gov/news.release/pdf/cpi.pdf
