You can't trust any of those figures don't forget in 1997 (and again in 2010) & also different forces often have different "policies" on recording, we got a new government who then changed lots of reporting & recording rules.
Many things that are not serious assaults are now being recorded as such. Government figures like the police crime reports are notorious for their bias.
Unfortunately as I'm sure you know when you have political parties using such things to point score & set agendas you'll never get reliable figures.
Probably the lack of attacks on schools is because it promptly caused government to ensure schools no longer have open doors & you now have to be buzzed in, that wasn't as prevalent back then.
There's probably a bit of everything in it along with socioeconomic factors too.
