Six out of Ten women in Nigeria are Unfaithful?

I don't know what to say to this news which has been floating around recently. The Durex Sexual Well-being Global Survey conducted by the condom manufacturer, interviewed 26,000 people in 26 countries and ranked Nigerian women as the most unfaithful in the world.

Daily Times reports  that "the top two countries with cheating women are Nigeria, with 62 percent, and Thailand, 59 percent. 39 percent of Malaysian women also confessed to having betrayed their partners. Russian women came fourth at 33 percent while Singaporeans are fifth at 19 percent." From a link I got in the comments, I went to the Durex survey methodology page where I found the following information.

- The survey was conducted during August and September 2006 by a research agency called Harris Interactive.
- Random samples of participants aged 16 + or 18+ were sent an email invitation to participate in the survey.
- The sample was primarily sourced from Harris Interactive’s internet panel.
- An online approach was adopted in 25 countries: Australia, Austria, Brazil, Canada, China, France, Germany, Greece, Hong Kong, Italy, Japan, India, Malaysia, Mexico, Netherlands,New Zealand, Poland, Russia, Singapore, Spain, South Africa, Switzerland, Thailand, UK, USA.
- For Nigeria a face-to-face/self completion approach was adopted, due to the low use of internet and telephone.
- They used a sample size of 1,000 for the majority of countries surveyed.

Which brings me to my conclusion. A sample size of just one thousand is just too small to reference a population of at least 70million women in Nigeria. Also, a face to face interview method tells me that the sampling was not as random as the other countries. I think the location and manner this method leaves it open to more prejudice than an online sampling. For instance, it is very probable that only women in Lagos were sampled, or women found at sexual health clinics, or women who might not really understand the questionnaire. Vera Ezimora also thinks Durex left out the fine print.

With all that said, I'm not vouching women as saints. Women cheat, and where it is likely that men cheat a lot, it is also more likely that the numbers of unfaithful women will be high. Is this the case in Nigeria? You tell me.
