let me explain what I mean by my locations demographics/statistics\mental health standards... by that I mean here in the USA each mental health agency keeps records on their clients. and then tallies that information into stats (statistics)

example....(not using any actual figures here...just plucking a number out of the air for an example....

if a mental health agency sees 100 clients. their statistics may be something like...

70 clients depressive disorders
10 clients with bipolar disorder
5 clients with DID

each one of these demographics are further broken down depending upon what the reports need..

5 DID cases range of alters varies, all reported abuse in these 5 cases are before the age of 5.

ok then the mental health agencies take these statistics based on their own clientelle of how many they see and what the overall mental disorder break down is....and send it on to where ever the paperwork says that the periodic census is being correlated for the state census bureau.

doing reports like this (how many clients agencies have, an average of what mental disorders are being treated and how many....) in part is how the government aid is given to the mental health system and given out per agency per fiscal year.

these are the demographics and statistics Im talking about when my posts say this. Im not talking based on individual people ....here in america we go through census taking of every household, person and agency\business on a yearly basis.

here in my location the documented statistics\demographics are that DID begins under the age of 5 due to extreme abuse.

you can find out what the statistics /demographics in your location and the agency in which you receive treatment by talking with your treatment provider or visiting your library. a librarian can show you where the most recent census statistics are that was done in your location.

note though that these census reports will only show what has been reported. if your mental health agency doesnt participate in your nations census taking then they may not have any demographics/statistics for you.

also note that the census is an average. it doesnt go by individual... due to privacy laws treatment providers can not tell the census bureaus something like patients name address and a breakdown of that persons files. when mental health agencies here in america fill out their forms they cant say client amandalouise, DID, alter number 1 is 8, alter number 2 that appeared to us was 10, alter number 3 that appeared to us was 5....this caused this alter to be created that caused that alter to be created...

census taking is a process of reporting the basics...number of clients treated at this agency, a break down of mental disorders treated over the course of the past year.... averages...

all this doesnt mean like in your case there isnt people with DID of first abuse at or after age 5. it just means thats what the statistics\demographics show in my own location.

I hope that helped to clarify my post for you.
