What are the most dominating cities in their countries?

San Juan metro area accounts for more than 3 quarters of the population of Puerto Rico. Same with the Kuwait City metro area in Kuwait.

What: Population distribution between the largest city, the urban area without the largest city, and the rural population. Metro area is meant by the largest city in most cases.
When: 2019
Where: Top ranking countries except one-city countries (like Singapore) from the whole world. Some countries with a total of 26 million inhabitants were excepted because they do not have needed statistics in the Worldbank database. Many of them are small, possibly one-city countries.

Are the largest cities dominating their countries?

Are the largest cities dominating their countries?

There are countries where they do, with notable examples being Kuwait, Puerto Rico, Djibouti, Mongolia and Uruguay.

Since rural populations are declining everywhere, relative weights of urban populations, as well as those in the largest cities, are increasing, so largest cities now are more dominating than they were in the ’60s.

The most concentrated region seems to be East Asia, but that is because they have Hong Kong and Macao with almost 100% of people living in the only city.

What: Median proportion of the population in the largest city, the urban area without the largest city, and the rural population.
When: 1960 and 2019
Where: The whole world, with some exceptions having a total of 26 million inhabitants, the biggest being Botswana, Lesotho and Slovenia. Many of those exceptions are small, possibly one-city countries which do not have needed statistics in the Worldbank database.

Is Europe reducing unrecycled waste?

Is Europe reducing unrecycled waste?

Whether the total amount of waste would decrease or increase, it would still be nice if amounts of UNRECYCLED waste decreased. If compared to 2004 it decreased, but if compared to 2010 it is increasing in spite of higher recycling rates.

What: Waste recycled or refilled in total waste generated.
When: 2004, 2010 and 2016
Where: Europe

Which type of waste is best recycled or refilled?

Which type of waste is best recycled or refilled?

Metallic and glass waste. It’s probably quite easy to reuse metal and refill glass containers.
The least recycled are mixed ordinary wastes of which almost half are generated by households (as seen in the previous chart).

May it be the motivation for sorting – if more mixed waste became recyclable waste, more would be … recycled.

What: Waste recycled or refilled in total waste generated.
When: 2016

What kind of waste do people generate?

What kind of waste do people generate?

Mostly mineral and solidified wastes from business activities. Here goes waste from construction and demolition activities, combustion wastes, soils.
Mixed ordinary wastes are the second – almost half of it is generated by households.
The only type of waste where households produce more than half of the output is plastic.

What: Waste generated, tonnes.
When: 2016
Where: European countries

Do richer countries produce more waste?

chart planet Posted on by

If the waste generated per GDP euro is compared to GDP per capita, then no trend is visible. Seems that required additional waste for additional euro per capita is more or less fixed (at least in Europe) except for 4 countries.

Math goes like this: to increase GDP per capita in 1 €, the total amount of waste should increase by w/(GDP per capita), where w is the current total amount of waste. Then the additional amount of waste is equal to (waste per GDP euro) * population.

What: Waste generated, tonnes per GDP euro & GDP, chain-linked volumes (2010), euro per capita
When: 2016
Where: European countries.

Do richer countries produce more waste?

If waste generated is compared to GDP (both per capita), then some positive trend is visible, but still there are too many outliers to draw conclusions. Amounts of waste each country generates depend on specific features of that country.

Does self-observation help to improve?

Does self-observation help to improve?

This is my last data selfie for now.

I tracked down the time when I start my working day, what percentage of weekly goals I do achieve and whether I do many other daily routine things (meditation, exercise, proper meal, not checking social media after 6 p.m. etc.) which I aggregated into “Level of discipline”.

During the time of self-observation I began to wake up and start working earlier, I started to achieve more goals, but this “discipline” thing did not improve. I guess that trying to do many “useful” things during the day is not as useful and productive as it may seem.

What: Weekly average time of starting to work, the proportion of weekly goals achieved, and “level of discipline” measured in points. Moving averages are calculated using 5-week intervals. There are omissions in the data, as one may see.
When: 38 weeks during 2019-2020

Is discipline helping to be more productive?

Is discipline helping to be more productive?

This is another data selfie based on my own observation of myself.

I tracked down how disciplined am I based on how well I stick to my daily routine and also how much of weekly goals I do achieve. There is a visible positive correlation, but two facts leave me unconvinced that discipline is really useful: 1. When I am the least disciplined, my results are not really bad, at some weeks I even managed to achieve 100% 2. When I am the most disciplined, at some weeks I had results that are among the worst.

I guess that when I concentrate too much on those “daily routine” and “discipline” things I might be more motivated, but then I have less time for actual work on my goals. After those weeks of tracking my results, I dropped the effort to stick to the daily routine completely. And I believe I am as productive as I can be.

What: The proportion of weekly goals achieved and “level of discipline” measured in points. Discipline points are binned into arbitrary intervals, and the white gradient shows median at its brightest point.

Is waking up earlier better?

Is waking up earlier better?

In this world of selfies I make data selfies. I documented my daily routine and weekly goals for 38 weeks and how I have some data to make conclusions on.

According to my own observations of myself the earlier I wake up and start working, the more weekly goals I achieve. Starting the work at 10 a.m. yields better results than at 9 a.m., but there were only 3 weeks when I woke up so late on average and even those were affected by a single day when I slept until noon after some kind of all-night activity.

When I wake up early my body and mind are ready to work at once – I’m definitely not an owl.

What: Weekly average time of starting to work, and the proportion of weekly goals achieved. Time is binned into intervals by 1 hour, and the proportion is averaged.

How are China’s corporations doing compared to the rest of the world?

chart planet Posted on by

They’re doing well on the internet. China’s Tencent and Alibaba are among the top 10 for 4 years already.

What: Non-USA companies that are in the top 10 public traded companies by market capitalization every year. Saudi Aramco is not included, because only a small fraction of its shares are traded publicly.
When: 1997-2020Q2
Where: I hope it’s the whole world except the USA.
