15 things we learnt from the Terrorism decoded series

Terrorism, and the reactions to it, has changed Kenya in a number of ways and brought unsettling realities about life in Kenya out into the open. 'Terrorism Decoded', a four-part interactive series, has reported on Operation Linda Nchi, the deadly attacks before and after the incursion, and the effects insecurity has had on Kenyans and their livelihoods.

Here are 15 important facts that the project has revealed. Click on the links to interact more with the data and visualisations.

Al-Shabaab militants have perpetrated half of the 448 acts of terrorism that have happened in Kenya since 1975.

Attacks in the 45 months after Operation Linda Nchi began were 10 times the number in the 45 months before the offensive.

The Westgate Mall attack in September 2013 was one of the 20 worst terrorist attacks in the world that year.

From the 40 charter planes that used to arrive in Mombasa every week from Europe at the peak of tourism in 2011, only four arrive each week in 2015, a drop of 90 per cent.

Since 2012, Germany has been the premier tourist source market for Kenya.

Visitors from the US increased by 16 per cent from 254,000 in 2010 to 294,000 last year, despite the US government issuing at least eight travel advisories during that period.

One out of every three government-employed teachers in the northeastern region, equivalent to 2,177 teachers, have kept away from their duty stations for up to eight months due to attacks by Al-Shabaab militants.

A person living in Nairobi is 11 times as likely as a resident of Mandera to have attained secondary level education and higher, partly because perennial insecurity in the northeastern region contributes to low school enrolment and completion.

Only one-third of residents of Mandera and one in four residents of Wajir and Garissa have received formal education.

Turkana (3.3 per cent), Wajir (4.0 per cent) and Mandera (4.7 per cent) have the lowest level of secondary-level education countrywide.

Ten years ago a Kenyan was three times as likely to be robbed and two times as likely to have their car stolen as they are today. This could well be an unexpected gain of the efforts by private citizens, businesses and organisations to fortify themselves against the threat of terrorism.

For every police officer in Kenya, there are eight security guards due to the rise in demand for private security services due to the terrorism threat.

Kenya’s partners have given more assistance to the military. This year, the US government will allocate Sh10 billion to Kenya in counterterrorism assistance, more than double the amount it gave last year.

Training colleges for the Kenya Police, Administration Police and the General Service Unit saw increases of 46 per cent, 45 per cent and 16 per cent respectively in the 2015/2016 budget.

Security has impacted heavily the operational costs of venues that attract large crowds of people, such as churches and shopping malls. Security now constitutes as much as 25 per cent of operating costs, by some estimates.
