> Women who write the software that runs on mainframe computers earn on average 72 cents per dollar earned by their male counterparts, according to research conducted by Glassdoor Inc., the online job information firm.

Do they really mean mainframe computers? If so, that is a tiny and unrepresentative portion of all computer programming. If not, it's a hell of a typo.

Yes, because they give different statistics for "software engineers" and "mobile developers". Strange distinction and strange wording in the title, to say the least.

> However, not all tech jobs pay men and women so differently. Among mobile developers, there is just a 2.9% gap between the average salaries for men and women after adjusting for age, experience and other factors. For software engineers, men on average make 6% more than their female colleagues.

The biggest pay gap is between different cities and countries. My girlfriend's sister is a junior developer in India and makes about $300/month.

$400 USD is equal to 26,766.18 Indian rupees. Adjusting for purchasing power parity[1], that will buy as much as $1,526 in the US, so her yearly salary is equivalent to just over $18,000. Which is still surprisingly low.

Note I updated the amount to $300 per month (after asking my GF again to confirm). She makes 20,000 rupees per month.

Wrong. Wet nurses do.

Heh. Well, so do sperm donors.
