Social Policy Simulation Database and Model allows you to make a good estimate, as it draws on tax data, so I just crunched these out. For 2010, the top 1% (works out to a household income over $366,717) took 10.5% of total income (market income plus investment income plus government transfers). The next 4% took 12.0%. Overall, the top 10% of households (income over $148,241) got just under one-third of the income (32.9%). The real action, though, is around wealth (who owns and controls what), not just the distribution of annual incomes (wages, salaries and bonuses made in a year). For wealth, we only have Canadian data for the top 10%, and only as far back as 2005 ( Morisette and Zhang 2006 ): A key point is that wealth is much more unequally distributed than income. These numbers are striking, with 58% of wealth in the hands of the top 10%. But we hit a bit of a wall when it comes to looking further up. There does tend to be a bit of fractal pattern that happens with distribution, so if the top 10% get 58% of the wealth, a rough estimate is that the top 1% would get 58% of the income of the top 10%, so about one-third of the total wealth. Meanwhile, the bottom half of households have a teensy 3% of total wealth, with the bottom 10% completely underwater (liabilities greater than assets, or negative net worth). To probe the nuances of income and
