I was in Ieper yesterday at the Menenpoort and I though by myself. I see a lot of "local" regiments then I tough of something I read in the newspapers arround D-Days that the American Military stopped with "local/friendship" regiments after D-Day because the youth of certain communities where decimated. Now is my questions is did the British stop with these regiments after WW1, because they already saw that the youth was decimated?
Edit: Sorry for the error in the title.
I'm assuming you are referring to what were called "Pals battalions"; units that were collected from the same local recruitment posts to allow volunteers to be with people they knew already at the front. http://en.wikipedia.org/wiki/Pals_battalion
I'm afraid I can't find another source at the moment, but after conscription began early on in 1916 new Pals battalions were no longer formed and those that remained were later absorbed into larger formations.
However, that is not to say that British military units do not still have a regional focus in some cases and celebrate regional heritage and recruit from certain areas. One offhand example I could give you is the Yorkshire Regiment.
Although things have changed a great deal since 1918 (and will changed even more under the Army 2020 reorganization), the British Army has long followed a model of regional recruitment. Many British Army units have recruiting areas that are centuries-old.
Until their disbandment, the King's Own Scottish Borderers, for example, recruited men primarily from the south of Scotland. During WWII, battalions of the these regiments fought at Arnhem, in Burma, and in may other theaters of the war. Some units, like the London Scottish Regiment recruited from specific communities (in this case Scottish immigrants to London).
So, while the concept of the "Pals Battalion," with men from the same profession and neighborhood ended during WWI, the concept of regionally-aligned units remains strong to this day.
Each county used to have its own regiment of infantry as a default to join, often a county might have more than one and so there might be partitions within counties for recruitment, going back to the eighteenth century. After World War I the British Army has shrunk down considerably but still have a locality based system, just a lot less infantry regiments now; so you can see here the current system for infantry recruitment areas.
Charles Messenger's "A History of British Infantry: For Love of Regiment, Volume 2, 1915-1994" (Oxford, 1994) covers the majority of the period as the army shrank down and covers recruitment as it follows the series of cuts post 1918, significant growth for WW2 and then shrinkage once more.
