The old railway line in Phnom Penh is home to hundreds of sex workers who earn anywhere from $1-$5 from each 'client'. The rent for their homes (a spartan room on stilts above open sewerage) is around $20-$25 a month. This lady, once she gives birth to her child will most likely return to the trade within 2-5 days. If she and her child are to eat and have a place to live there is no option.
