oh yawn ukipechochamber you do go on and on don't you?
You have been given links to research showing the socio-economic benefits of diversity to the life of a country. You have been given links to show the benefits of immigration and diversity to social capital. But you still claim you have not been given what you asked for or that this is not enough to show the social benefits. Bit sad that you still don't seem to actually understand what is written in front of you. Or, at least, that you choose to deliberately misunderstand.
Yawn, yawn, yawn.
You really are like a stuck record.
By the way you never asked for evidence that proves diversity leads to greater social cohesion. You asked for evidence to disprove your assertion it causes a lack of (long term) social cohesion.
There is a subtle difference of which you may - or may not - be aware. You keep being given what you asked for then moving the goal posts just ever so slightly to keep up the pretence that no-body has yet managed to answer your questions.
Do you really, really think anyone is fooled by you?
So now you want evidence that shows the positive, strengthening effects of multiculturalism on society?
Social fragmenation is higher in areas with economic deprivation, high unemployment, poor housing, competition for resources etc. Diversity can therefore become a factor - though not the defining factor or the dominant factor - in social fragmentation in areas which are already under stress.
Social cohesion does not refer to an absence of diversity but to bonds that give people a feeling of unity at community and national level. This is generally accepted to include common values, civic order, participation in a democratic process, a sense of belonging and equal opportunities. However since there is no single, accepted definition for social cohesion, or agreement on the indicators to measure it, research varies considerably. Research on the impact of diversity on social cohesion in Europe is therefore mixed. There is research that says that it is detrimental to social cohesion, there is research that says it does not have a negative impact, there is research which says it has a positivie influence. It very much depends on what indicators are used in the research.
However a common factor in British and European research is that it hasn't been able to conclusively resolve whether it is diversity per se or actually income (poverty) which is the issue. It may well be that income disparity rather than diversity are the cause of social fragmentation. This seems to be what European and British research leans towards showing.
Fieldhous and Cutts for example concluded that ethnic diversity assists in building more cohesive communities. Both Laurence and Heath, and Letki concluded that there is no strong evidence that diversity has a negative impact on social cohesion when economic deprivation is taken into account. Sturgis et al. and Twigg and Taylor both highlighted the fact it is economic deprivation rather than diversity than leads to social fragmentation. These findings are supported by the governments policy research too.
So.... if diversity and immigration provide an economic benefit (proven by research) and economic deprivation causes a loss of social cohesion, it could be suggested that social cohesion will increase with immigration due to the improved economic circumstances. Oh goodness, gracious me.
Social cohesion is generally accepted to indicate a sense of togetherness or belonging: the extent to which people feel accepted and able to contribute in their community.
It's ironic then isn't it ukipechochamber that people like you help foster the feeling in people that they do not belong, are not welcome etc are actually damanging to social cohesion.
You, it seems, are part of the problem. You are not the solution.
