The answer isn't stable.
Right now (in 2010), this means 1994.
If you are precisely 16 yo that is.
If by 16 you mean at least 16 but less than 17 then the answer is (again in 2010): 1993 or 1994.
If I am currently 16, then you were born 16 years before the present year. Therefore, the year you were born in would be the current year minus 16.
People turning 16 in 2015 were born in 1999.
You were born in 1997.
1994
If you were born earlier in the year, you would currently be 16. If you were born later in the year, you would be turning 16. (This is with a current date of 2012.)
If I am currently 16, then you were born 16 years before the present year. Therefore, the year you were born in would be the current year minus 16.
You were born in 1992
People turning 16 in 2015 were born in 1999.
In 1994
1996
You were born in 1997.
2010 - 16 = 1994
subtract 16 from 1992
1996
1994
if your 16th birthday is in the year of two thousand and nine 2009-16=1993 you were born in 1993
If you were born earlier in the year, you would currently be 16. If you were born later in the year, you would be turning 16. (This is with a current date of 2012.)
