I was born in 1956. At that time, the phrase "birth control" was younger than I am now, and "The Pill" would not be approved for contraceptive use in the United States for another four years.
During my childhood, the notion that individuals might choose the number of children they engendered was still very controversial in and of itself -- contraceptives were not available to married women in all US States until 1965 (I was age 9), and not available to unmarried women in all States until 1972 (I was 16). Roe v. Wade would not be decided for another year after that.
I've wrestled a bit with how to tell my personal story without invading my parents' privacy -- so I'll make it brief and discrete: After I was born (the fourth of four childen -- an "average" size US family in those days), my parents chose birth control.
I believe that, because of this, I grew up in a family that had better economic viability, a higher level of physical and mental health, and a better quality of life in general. Read more of this story at Shakesville...
