[Summary sentence: what the chart is about]
The bar chart depicts total UK wealth, excluding liabilities, measured in billions of pounds, between 2000 and 2010 and broken down by household, government and business sectors.
[Summary sentence: results]
Total national wealth increased over the period with most wealth concentrated in the household sector.
[Main points of the data:]
Total wealth generally followed the fortunes of household wealth, but only matched it in 2003/2004. Overall net worth grew from nearly £4000 billion in 2000 to nearly £7000 billion by 2010.
Household wealth grew from £4.5 billion to £7 billion over the period despite a slight dip in 2008/2009.
Government wealth contributed negligibly to UK net worth remaining almost static at well under £200 billion before tailing off after 2008 and showing no contribution in 2010.
Business wealth displayed a marked contrast to household wealth. Of all the sectors it fared least well, being consistently in the red for the entire period to the tune of nearly -£1000 billion at times and demonstrating erratic variation from year to year.
