No, not necessarily. I work in the field so know a bit about the data, and theoretically there can be a number of reasons why the figues are high...the best thing to do is to contact a PCSO and ask them to explain.
For example, there could be a couple who regularly have domestics...this could cause a spike in assaults/asb etc., when there could have been 10 reported incidents from them or their neighbours. One crime could be recorded as a number of crimes...for example one incident where a drunken bloke damages three cars would be recorded as three separate criminal damage incidents, when it could be a one off. Also some crimes are opened as one thing, and closed as another...you can ask what is used as I can't remember, but as an example, there's an elderly lady near here who has dementia and reports burglaries frequently but there hasn't been one...the call will be opened as burglary but closed as a non crime...I would think they'd use the closing codes as opposed to opening though.
Asb is a dodgy stat, as its not properly defined...what you consider as asb and what I consider as asb can be totally different. If you feel that something is inappropriate then it would be logged as asb. We get a lot of asb calls whch are only poor kiddies playing football in a street or some other nonsense that isn't what most would consider as asb, but it would have to be recorded as such due to its wide definition.
Also worth checking if you live near a police station...sometimesit can appear that there are loads of crimes near police stationsbut only because of reporting error where the locationof the report and not the incident has been entered...
Personally I'd look back at a few month's worthof the data, and then ask a PCSO about it...also, you can use insurance quotes to get an idea...just change the postcode for house insurance and car insurance and there will be a dfference related to crime in the area and a number of other factors too.
Its always good to visit an area at a number of different times, amd if you can, attend a local PACT meeting (where the police and council are present andlocals raise issues with them)...they are VERY informative!
