The world population is 6.8 billion people.

Judged as of the date in 2010 when the statement was made, against contemporary world population estimates (UN World Population Prospects, US Census Bureau world population clock or similar) for that date. The claim is rounded to one decimal place. True: estimates for that date are between 6.75 and 6.85 billion. Mostly true: between 6.70 and 6.95 billion. Mixed: between 6.6 and 7.0 billion but outside the mostly-true band. Mostly false: between 6.4 and 7.2 billion but outside the bands above. False: outside 6.4–7.2 billion.

1. E1 [PDF] Population and families - the United Nations United Nations Statistics Division (The World's Women 2010)

   “The world’s population in 2010 is estimated at nearly 7 billion people – more precisely at 6,908,688,378 – which is almost three times the population estimated in 1950”

2. E2 World population - Wikipedia Wikipedia

   “The United Nations and the US Census Bureau both give different estimates – according to the UN, the world population reached seven billion in late 2011,[114] while the USCB asserted that this occurred in March 2012.[123]”

E1, the UN Statistics Division's The World's Women 2010, estimates the world's population in 2010 at 6,908,688,378, or about 6.91 billion. That is above the 6.75–6.85 billion band for "true" but within the 6.70–6.95 billion band for "mostly true". E2 is consistent with this: it says the UN put the seven-billion mark in late 2011 and the US Census Bureau in March 2012, so the 2010 population was below 7 billion. The exact date of the statement in 2010 is not given, but a 2010 estimate of about 6.91 billion places the claim in the mostly-true band.
