3. Poverty and Social Exclusion in the United Kingdom: The 2011 Survey
The largest ever research project on Poverty and Social Exclusion in the United Kingdom started on 1st April The ESRC (Economic and Social Research Council) has funded this 42 month, £4.3 million pound investigation designed to advance the ‘state of the art’ of poverty and social exclusion measurement.
The research team is one of the most experienced in poverty measurement methodology ever assembled in the UK. It is a major collaboration between researchers at Heriot-Watt University, the National Centre for Social Research, Northern Ireland Statistics and Research Agency, Open University, Queen's University Belfast, University of Bristol, University of Glasgow and the University of York.

4. Background
Every decade since the late 1960s, UK social scientists have attempted to carry out an independent poverty survey to test out new ideas and incorporate current state of the art methods into UK poverty research.
Poverty in the UK survey (Peter Townsend and colleagues),
1983 Poor Britain survey (Joanna Mack, Stewart Lansley)
1990 Breadline Britain survey (Joanna Mack, Stewart Lansley)
1999 Poverty and Social Exclusion Survey (Jonathan Bradshaw and colleagues) and its 2002 counterpart in Northern Ireland (Paddy Hillyard and colleagues)
2011 Poverty and Social Exclusion in the UK -

5. Objectives
To improve the measurement of poverty, deprivation, social exclusion and standard of living.
To measure the change in the nature and extent of poverty and social exclusion over the past ten years.
To produce policy-relevant results about the causes and outcomes of poverty and social exclusion.

11. The Costs of Poverty in the UK

13. Economic Cost of Child Poverty in the UK
Child poverty costs the UK at least £25 billion a year, (equivalent to 2% of GDP) including £17 billion that could accrue to the Exchequer if child poverty were eradicated.
Public spending to deal with the fallout of child poverty is about £12 billion a year, about 60 per cent of which goes on personal social services, school education and police and criminal justice.
- The annual cost of below-average employment rates and earnings levels among adults who grew up in poverty is about £13 billion, of which £5 billion represents extra benefit payments and lower tax revenues; the remaining £8 billion is lost earnings to individuals, affecting gross domestic product (GDP).

15. Child Poverty in the UK
The UK Government is committed to tackling the problem of child poverty. In March 1999, the Prime Minister Tony Blair set out a commitment to end child poverty forever:
“And I will set out our historic aim that ours is the first generation to end child poverty forever, and it will take a generation. It is a 20-year mission but I believe it can be done.
The Child Poverty Act 2010 has placed this policy commitment into UK law

16. Child Poverty Act 2010
Places in legislation the commitment to eradicate child poverty by 2020, this means that UK Secretary of State will have a duty to meet the following child poverty targets:
Relative poverty: Less than 10% of children living in relative low income poverty by 2020.
Material Deprivation: Less than 5% of children living in combined material deprivation and low income.
Absolute low income: Reduce the proportion of children who live in absolute low income to less than 5%.
Persistent Poverty: percentage of children living in relative poverty for three out of four years (target level to be set by the end of 2014 as data are currently unavailable)
Requires the UK Secretary of State to publish a UK child poverty strategy, which must be revised every three years.

17. Definition and Measurement

18. Scientific Definitions of Poverty
Poverty can be defined as;
Command over insufficient resources over time
The result of poverty is deprivation

19. Peter Townsend’s concept of dynamic poverty
“poverty is a dynamic, not a static concept…Our general theory, then, should be that individuals and families whose resources over time fall seriously short of the resources commanded by the average individual or family in the community in which they live are in poverty.”
Townsend (1962, p 219)

20. Uni-dimensional Poverty Measurement - Low Income in Britain 1961-2003

21. Foster, Greer and Thorbecke (FGT) index
where:
Pα is the level of poverty
n is the population size
Q is the number of poor
z is the poverty line
yi is the per capita household income
and α has a normative value that can be set at different levels according to the importance one attaches to the lowest living standards.

25. Lotka-Volterra (Predator-Prey) Model
If we let R(t) and L(t) represent the number of rabbits and Canadian Lynx, respectively, that are alive at time t, then the Lotka-Volterra model is:
dR/dt = a*R - b*R*L dL/dt = e*b*R*L - c*L
where the parameters are defined by:
a is the natural growth rate of Rabbits in the absence of predation,
c is the natural death rate of Lynx in the absence of food (Rabbits),
b is the death rate per encounter of Rabbits due to predation,
e is the efficiency of turning predated Rabbits into Lynx.
This is a simple first order non-linear differential model – when extended to multiple species it exhibits chaotic dynamic behaviour
