The Government estimate has been proved to have been wrong on several occasions. My figures come from the OUMO, DWP data, independent sites like Full Fact, not the Guardian.
But just to make sure that you understand my points about benefits, which you and I have discussed before. I will use the Government's own data from Feb 2016 paper Statitics on Migrants and benefits.,
What proportion of benefit claimants are non-UK nationals?
"In February 2015, 371,220 working-age claimants of DWP benefits
(7.2% of total claimants) were non-UK nationals when they first
registered for a National Insurance Number (NINo). 113,960 of these
were EU nationals, 30.7% of non-UK claimants and 2.2% of total
claimants"
There are about 3 million EU immigrants in the UK. 113,960 claiming DWP benefits would means that it is 3.7% of EU immigrants.
Job Seekers allowance claimants:
"of these 91,700 were EU (excl. UK) nationals, 2.4% of
total claimants"
The data from January showed that only about 65,000 EU migrants were claiming JSA but we'll go with your 91,700 claiming JSA and to be even fairer we'll take from the 1.9 who are thought to be economically active in the UK, so that's 4.8% of economically active EU workers are on JSA, and as they make up 2.4% of the total claimants, but EU workers make up 5.7% of the UK workforce it means that they are under represented.
Tax Credits:
"317,800 of these claimants were EU nationals, 43% of total non-UK claimants and 6.8% of total claimants."
So again, EU immigrants living in the EU are 3 million, so 10.5 % of the total. Not 40%.
Take it down to the 1.9 million in the workforce then it only goes up to 16%.
Child benefit.
The figure available accounts for all immigration and isn't available for just EU, but it works out at 12.5% of the total, which again is lower than the level of total immigration.
The 40% figure quoted was actually for EU migrants in the first four years, and was an amalgamation of all benefits. It also has been heavily criticised because when including household benefits such as Child benefit and tax credits it includes those where one memeber of the household was an EU immigrant on being granted an NI number.
Also the figure given was an "estimate, they reckoned on between 37% and 46% of these very vaguely gathered figures, the OUMO using government data found even with the very broad range for estimating benefits usage that the figure was lower and probably about 27%.
This doesn't mean that the way you are using the figures is correct though, because this figure as stated is all benefits usage, applies to households not individual EU immigrants and doesn't account for length of time that benefits were claimed for, just gives the "first four years" so an immigrant employed for 3 years and paying tax who is made redundant and claims JSA for a month before getting another is included.
Its too woolly and vague a figure and Cameron's use of "reliant" on benefits
It also fails to take into consideration the wider context of things, from the Governments own paper again it is displayed that immigrants accounted for 2.5% of benefits the DWP administered in 2014 - mostly out-of-work benefits - in 2014, and 7% of tax credits, based on the HMRC definition discussed above. Again as EU immigrants make up 5.7% of the workforce this is broadly in line with what is to be expected for WTCs and shows that they are under represented in terms of unemployment benefits.
The DWP analysis says EU migrants on “in-work” benefits cost the taxpayer £530m in 2013 representing a modest 1.6% of the year’s total tax credit bill, again as they make up 5.7% of the workforce this shows that they are under represented here in terms of spending.
Studies broadly show that EU immigrants contribute more than they have taken out in any fiscal spending, EU 8 countries by £1.12 for every £1 spent and EU 14 £1.64, this is fromm looking at a range of different surveys. HMRC data shows that the EU immigrants who arrived in the financial year 2013/2014 contributed £2.5 bn more to the exchequer than they took out in benefits.
On Brits abroad? Studies of Expat communities in Spain have found that retired UK nationals are twice as likely to be hospitalised than their Spanish counterparts of the same age. So they are having an impact. Interestingly EU citizens are less likely to use health services than their British counterparts because of what is called the healthy migrant effect, and Oxford University found than increases in immigration caused lower A and E waiting times and lower elective treatments waiting times in almost all areas, except very deprived ones outside of London, and only then between 2004 and 2008 when this trend ceased.
Your arguments are crap and stand up to no scrutiny, and even your use of data is deeply flawed.
