Note: This is the first blog of a series of blog posts on data availability within the context of TCdata360, wherein each post will focus on a different aspect of data availability.
With open data comes missing data. We know that all indicators are not created equal and some are better covered than others. Ditto for countries in which coverage can range from near universal such as the United States of America to very sparse indeed such as Saint Martin (French part).
TCdata360 is no exception. While our data spans across over 200 countries and 2000+ indicators, our data suffers from some of the same gaps as many other datasets do: uneven coverage and quality. With that basic fact in mind, we have set about exploring what our data gaps tell us — we have 'data-fied' our data gaps so to speak.
In the next few blogs we'll explore our data gaps to identify any patterns we can find within the context of the TCdata360 platform — which countries and regions throw up surprises, which topics are better covered than others, which datasets and indicators grow more 'fashionable' when, and the like. In this first blog, we’ll look at data availability at the country level.
The Big Picture
TCdata360 classifies its data into four high-level topics: Innovation, Investment, Sectors, and Trade (plus Economy). We’ll be looking at the indicators and datasets under these 4 topics for this whole blog series.
Overall, data availability has increased over time at a compound annual growth rate (CAGR) of 6.8%. CAGR can be thought of as the growth rate which allows the initial value to grow to the latest value, assuming that the growth rate is compounded throughout the entire time period.
To get a sense of the overall increase across countries (and to be able to compare them somewhat consistently), we computed for data availability over time by taking the percent of available indicators per country per year. This is what the pattern looks like when we take the median across all countries.
