>>"Sweden has 9 million people that live in 4.5 million households"
Wow, what a statistic! That implies each household, on average, has only 2 people. That infers that each couple has less than a child, or there are a lot of single parent family. I wonder if the Swedish population has been growing at all.
We have noticed that in get togethers with friends that SodaStream comes up in the conversations, without any prompting on our part. The company advertising seems quite good. And several of the women have said they have purchased one, or plan to do so.
Sweden has 9 million people that live in 4.5 million households.
Assuming that everyone living together in one household shares one machine instead of buying a separate machine for each person, then 4.5 million is the correct divisor for calculating market penetration.
