This is my personal anecdotal observation from having worked with the public for 30 years, spent many years teaching Sunday School, tutoring for our church, and the past 3 years as a cub scout leader. A Stanford University professor did e-mail me and told me that studies have *never* been done that evaluate the amount of learning acquired from "afterschooling". My bet is 99.99% of what a child learns is due to afterschooling and happens IN THE HOME!
Do you have any studies supporting this? Do you have any studies showing that home school students earn more money, are more mentally/ emotionally stable, or perform better in college?
Yes, these studies have been done regarding homeschoolers who are now adults. Adults who have been homeschooled are far more likely to vote, have higher levels of post high school education, are far less likely to be divorced, are more likely to be married and have children, are volunteers in the community at significantly higher rates, and they simply couldn't find any homeschoolers who were on welfare...zero!.

By the way,...I find it appalling that we spend up to $30,000/ year/child for socialist-entitlement schooling and NO ONE knows if it is effective in the least. Without measuring the contribution of afterschooling NO ONE can say, one way or the other, if government school teach anything at all!!!!
This "study" you posted does not really hold much water.
First off it is eleven years old.
Second it was commissioned by by a home schooling organization and done by the president of another home schooling group. This is the equivalent of the DNC commissioning Debbie Wasserman Schultz to poll its members to see who would make a better candidate, Romney or Obama.
Third while the same size is a good representation it is skewed. They sampled 7000 students 5000 of which had been home schooled for 7 years or more. That means that Sixty six percent of the sample were home schooled.
These two sites say that the percent of students being home schooled is somewhere between 3-4%.

The second site says that there are a number of people that they were not able to get information on and estimates that the actual number is higher. even if you say it is double (8%) the sample is still skewed.
Finally I asked for STUDIES plural.
One would think that you would have dozens at your finger tips.
