United States vs China: number of internet users

Here are a few charts I put together when researching the reasons for eBay's failure in China. It shows the total number of internet users in China and the United States.



As we can see, China accelerated past the United States from about 2006 onward. By 2008, China had comfortably overtaken the U.S. with 299 million users, compared with 225 million in the America.

These days, China has comfortably more than double the number of internet users than there are in the U.S. It has 571 million internet users, whereas the U.S. has 254 million users.

But the raw count of internet users only tells half the story. Or should I say 42 per cent of the story. The other factor is the penetration rate i.e. the percentage of the population that use the internet.

The chart above shows the total population of both China and the United States. The darker colours represent the number of internet users and the lighter colours represent the non-internet using population.

Only 42 per cent of people in China were internet users in 2012. However this is a staggering rise considering that less than 2 per cent of the population were internet users in 2000. The amount of headroom remaining for growth is phenomenal. No wonder so many Western companies want a piece of this big, tasty steamed pork bun.

Having been to China a few times I can personally vouch for the ubiquity of the internet and associated technologies such as smartphones. Certainly in the larger cities such as Beijing, Shanghai, Guangzhou and Shenzhen.

However, I have also experienced the Great Firewall of China at first hand. Sites such as Facebook and Twitter are inaccessible in China. Local alternatives, such as Sina Weibo, with over half a billion registered users, have cropped up as a consequence.




So, the most popular non-Chinese sites are blocked in the country. The Chinese language makes Chinese sites essentially inaccessible for outsiders. Yet, as we can see above, almost a  quarter of the world's internet users are in China. And that percentage is growing fast. Where exactly is the true internet again?

A heatmap of driving times in the Motor City

Here is an interactive driving time heatmap for Detroit. It visualises the time it takes to drive from Downtown Detroit to its outlying neighbourhoods. I thought it would be cool to see the artery effect of fast roads visualised on a choropleth. As the Motor City, I also thought Detroit would be an obvious choice for this.

As expected, the major roads and highways do indeed create an artery-style effect in the map below. All of Downtown is within five minutes driving time. Midtown, Corktown, Woodbridge, Eastern Market, New Center and North End are all within a mere ten minutes drive.

The map also makes it possible to spot places that are pretty inefficient to get to. For example, the Charter Township of Clinton to the north-east takes about 35 minutes to get to and is 25 miles away. This is visible as the swathe of green encompassing the township on the map. However, the Plymouth Charter Township, west of Downtown, is the same distance and takes ten minutes less time driving time.




Another interesting quirk of Detroit is that its Downtown area straddles the US-Canada border. This means that although Windsor is only on the other side of the Detroit River, driving times are disproportionate to the short distance. We can see that visualised in the map above as the darker colours emanate out to the north-west, but do so to a lesser extent across the border.
