Map of apartment building management companies in Ljubljana

Share Button

Some time ago, I did an analysis of building manager companies for dnevnik.si. It was an interesting project, because there’s much controversy surrounding this topic. Some of these companies have been in bitter disputes with the residents and competing companies over their business, generating a lot of newspaper coverage.

We did a simple analysis to deterimine market shares and relative winners and losers in comparison to market leader. Here’s an image of final page in the newspaper. Click it to open the PDF.

We also did a lot of other stuff that didn’t find their way into the final article. I’m now publishing an interactive map, showing the distribution of these companies across town. There’s usually one per apartment building. For this map, I only processed the apartment buildings with more than one apartment, because that’s where business is.

Click on the image below to open the map in a new tab, or click here.

Click on a building, and a popup will display the address and relevant history. It’s also possible to choose a company, and the map will refresh, displaying only the buildings in the selected company’s management. There’s also a button to display only those buildings where managers changed in the interval from years 2005 to 2015.

There’s also a graphic showing how many buildings a company gained from other companies. Here’s a screenshot. Click will take you to the same page as image above.

The original dataset came from GURS, but then we were able to acquire an update from the city government. We decided to use that, because they gave us three different updates, each five years apart, from which we were able to calculate the differences. You can see them in table below.

  • total flats: how many apartments are managed by a company,
  • gained: how many flats were gained by the company from 2005 to 2015,
  • lost: how many flats were lost by the company from 2005 to 2015.

Original data is here.

The app helps the user find out where and when were traffic tickets issued in Slovenia, thus facilitating safer driving.
Ticket database is limited to territory of Republic of Slovenia.

Choose between these issued citations to show in app:
– parking
– speeding
– driving while using a cellphone
– ignoring safety belt laws
– unpaid toll
– DUI
and traffic accidents.

The app will locate you, fetch data about traffic citations issued in your vicinity, and show them on map. To see citations, that were issued somewhere else, click on map. Additionally available is summary of threat level, derived from statistical data, collected by government agencies. These are:

– overall threat assessment to be issued a citation, should you violate traffic laws
– average interval between citations issued at that location,
– date of most recent citation issued relative to data source update
– number of citations issued in vicinity
– distance to closest issued citation

And several statistical distributions of issued citations, such as:
– by days in week (how many on Monday, Tuesday, …
– by hours in day (how many in intervals between 9-12h, …)
– by months in year (how many on January, February, …)
– by weather conditions (how many in rain, snow, clear weather)
– by temperature (how many in temperature interval between 5-10 Celsius, …)

Same information si also available on address list, ordered by number of citations issued.

Data sources

Many thanks to traffic wardens, police, and other officials, who supplied the raw data, used to build this app:
– traffic wardens of Ljubljana,
– state police,
– DARS,
– Parkings of Ljubljana,
– traffic wardens of Maribor,
– traffic wardens of Kranj,
– traffic wardens of Celje,
– traffic wardens of Novo Mesto,
– traffic wardens of Nova Gorica

Data was acquired for time interval between 2012 and end of 2014.
The database contains is a little less than a million traffic citations.

Addresses with most registered companies in Slovenian towns

Share Button

There appeared an article, in which an attempt was made to expose questionable practices of some Slovenian enterpreneurs. The scheme is such: establish a company, perform some work, bleed it dry, then establish a new one and move all workers into it, at the same time avoiding paying benefits and a sizable portion of salaries. When the new company has server its purpose, establish a new one, and so on, as far as it goes. These companies are frequently registered at the same address.

The article says that there are as many as 120 companies registered in one residential building. But because of a weakness of the law, state inspectors can’t put an end to such practice.

I wanted to see these addresses on the map, so here’s an attempt. For every address with more than five companies, there’s a dot, with color and radius proportional with number of companies registered there. The biggest dots represent business buildings, in which a predominantly legitimate businesses reside. My data sources didn’t allow for filtering out just residential buildings.

You can see the standalone map here. (In Slovene.)

Interactive map showing addresses with most companies

Clicking on a marker displays a popup with a list of companies, sorted by date of establishment – youngest first. There’s also a chart of predominant business categories at that address. The categories that the article mentions as most prone to scheme in question, are Construction and Retail. So even of this map can’t really show the locations with these questionable companies, it can maybe help their discovery. If there’s a big dot with predominantly these categories, there’s a certain possibility that some of these fraudulent companies are there.

Most addresses shown here of course don’t have anything to do with any illegal activity.

Interactive visualization of Global Gender Gap Index 2013 report

Share Button

This is a brief visualization of Global Gender Gap 2013 Index report by World Economic Forum. As the report authors say,

The Global Gender Gap Index examines the gap between men and women in four fundamental categories (subindexes): Economic Participation and Opportunity, Educational Attainment, Health and Survival and Political Empowerment. Table 1 displays all four of these subindexes and the 14 different indicators that compose them, along with the sources of data used for each.

I thought it would be nice to try to visualize the data and make it as interactive as I could, and learn d3.js in process. I actually tried to mobilize all the data in the report, which one can see in graphical form by clicking on countries on world map, or selecting the categories in the dropdown.

There are several categories:

  • economy,
  • education,
  • health, and
  • politics

In addition to that, I calculated the differences between 2013 and previous years. These maps are also accessible through dropdown menu, or simply by scrolling up and down.

Copied straight from the report:

Economic Participation and Opportunity

This subindex is captured through three concepts: the participation gap, the remuneration gap and the advancement gap. The participation gap is captured using the difference in labour force participation rates. The remuneration gap is captured through a hard data indicator (ratio of estimated female-to-male earned income) and a qualitative variable calculated through the World Economic Forum’s Executive Opinion Survey (wage equality for similar work). Finally, the gap between the advancement of women and men is captured through two hard data statistics (the ratio of women to men among legislators, senior officials and managers, and the ratio of women to men among technical and professional workers).

Educational Attainment

In this subindex, the gap between women’s and men’s current access to education is captured through ratios of women to men in primary-, secondary- and tertiary-level education. A longer-term view of the country’s ability to educate women and men in equal numbers is captured through the ratio of the female literacy rate to the male literacy rate.

Health and Survival

This subindex provides an overview of the differences between women’s and men’s health. To do this, we use two indicators. The first is the sex ratio at birth, which aims specifically to capture the phenomenon of “missing women” prevalent in many countries with a strong son preference. Second, we use the gap between women’s and men’s healthy life expectancy, calculated by the World Health Organization. This measure provides an estimate of the number of years that women and men can expect to live in good health by taking into account the years lost to violence, disease, malnutrition or other relevant factors.

Political Empowerment

This subindex measures the gap between men and women at the highest level of political decision-making, through the ratio of women to men in minister-level positions and the ratio of women to men in parliamentary positions. In addition, we include the ratio of women to men in terms of years in executive office (prime minister or president) for the last 50 years. A clear drawback in this category is the absence of any indicators capturing differences between the participation of women and men at local levels of government. Should such data become available at a global level in future years, they will be considered for inclusion in the Global Gender Gap Index.

Score changes

Out of the 110 countries that have been involved every year since 2006, 95 (86%) have improved their performance over the last four years, while 15 (14%) have shown widening gaps. Ten countries have closed the gap on both the Health and Survival and Educational Attainment subindexes. No country has closed the economic participation gap or the political empowerment gap. On the Economic Participation and Opportunity subindex, the highest-ranking country (Norway) has closed over 84% of its gender gap, while the lowest ranking country (Syria) has closed only 25% of its economic gender gap. There is similar variation in the Political Empowerment subindex. The highest-ranking country (Iceland) has closed almost 75% of its gender gap whereas the two lowest-ranking countries (Brunei Darussalam and Qatar) have closed none of the political empowerment gap according to this measure.

Grouping countries according to flag similarity

This topic is apparently interesting enough that it warrants its own discussion on Quora. People there are relying on keen observational powers of human mind, but for this article, I tried to group the flags algorithmically.

I plotted the results on the map below. Countries with same colors have similar flags. The brighter the color, the bigger the group of countries with similar flags.

How I grouped the flags

I used a machine learning algorithm called k-means clustering. It’s really a rudimentary exercise, but the results are good enough to publish on this wee blog.

The algorithm accepts units to be grouped as vectors, so I had to vectorize the images first, that is to say, convert them in a long string of numbers. Each image was partitioned into a grid, then the average color  value for each cell was computed. The grid was 24 x 24 cells big. I found that enough for simple flags.  These color values were converted into HSB color space and experimentally weighted, then copied into a vector. These vectors were fed into the k-means algorithm with requested number of individual clusters set to 120 (there are 240 different flags). You can see results in the viewer.

Number of clusters was set experimentally, and the clustering is not perfect. For example, Canadian is grouped with some very unlikely lookalikes.
