[327-2] Mobile Teledensity / 行動電話普及率, 2009
Density of black lines indicate the penetration of mobile phones where more than 10% of the population own one. Sparse lines represent less than 50% ownership, semi-concentrated 50% to 100%, and most dense indicate more phones than inhabitants. Countries with more than double the world's average growth rate (CAGR) of 23% from 2002 - 2007 are encircled with bright dots. There are 4 billion mobile phones, 3 times the number of landlines.
黑線的密度代表行動電話的普及率，超過一成的世界人口都人手一支手機。稀疏的線代表不到50%的普及率，而密度適中的線條代表50%至100%的普及率，密度最高的線代表行動電話的數量已超過居民人數。採用亮色圓圈框起來的國家在2002至2007年的年複合成長率（CAGR）超過世界平均一倍以上。目前世界上存在著40億支行動電話，是室內電話數量的三倍。
