Check the fixture closest to the meter see if you have a problem there.
Also check the hose bibs with no hose attached.
Almost all fixtures have a filter, it could be possible that all your filters are clogged. Hose bibs have no filter, or screen, so if you have good pressure there I would suspect clogged filters.
You can get a cheap pressure meter to attach to the hose bib to read what pressure you have too.
The 'filters' I refer to are aireators and such. Just unscrew them and clean them. One on spout of each faucet. Also a screen on the hose connection to the washer.
