A majority of abortions happen in the very beginning stages. And 91%+ happen before your new cut off. It's like you belive everyone waits till the last second.
Most that happen that late is for medical reasons for the mother or the child. We all act based on the best scientific info even the article you posted isn't 100% fact.
Since you're using 2016 stats from the CDC, I'll augment that.
623,471 abortions were reported to the CDC in 2016.
Of that, 1.2% were performed at or above the 21 week point.
Gee. Only 1.2%? That's such a small number, right? No, that's not a number. It's a fraction.
The number of abortions performed after what some now say was past sentience was 623,471 * 1.2% = 7,482 (rounded).
That's almost 7,500 counts of murder in just one year.
By comparison, Chicago saw its highest number of murders in 19 years in 2016: 762. That's almost 1/10th the number of abortions at or above the 21 week point.
** Rule of thumb: When someone tries to make a point using percentages, fractions or ratios, it is beneficial to take time and look up the raw numbers for yourself. That often paints a much different picture -- which is usually what the presenter intended.
