Youth Power: 51% of Registered Voters Were Under 35 in 2017

Kenya's youth are the majority of voters. But only 9.2% of youth candidates actually won seats.

The numbers are striking. In 2013, youth voters (those aged 18-35) made up 46% of Kenya's registered voters, totalling 6,802,655 people. By the time voter registration closed ahead of the 2017 election, that number had surged to 10,001,826 — a jump of 47% in just four years. Youth voters now made up 51% of all registered voters, outnumbering older voters (9,609,597) for the first time.

The Youth Voter Surge: 2013 vs 2017

The growth was not gradual. Between 2013 and 2017, Kenya added over 3.2 million new youth voters to the register. This was driven by a combination of population demographics (Kenya has one of the youngest populations in Africa), targeted voter registration drives by the IEBC, and heightened political engagement among young Kenyans.

Here is the comparison:

• 2013: Youth voters: 6,802,655 (46%) | Others: 7,985,726 (54%)
• 2017: Youth voters: 10,001,826 (51%) | Others: 9,609,597 (49%)

The shift from 46% to 51% may seem modest, but it represents a fundamental change in the electorate's composition. For the first time, politicians could not win without the youth vote.

The 26-35 Age Bracket Explosion

Within the youth category, the 26-35 age bracket saw the most dramatic growth. In 2013, voters aged 26-35 numbered just 2,218,257, making up only 15% of the total electorate. By 2017, that same age bracket had ballooned to 6,552,176 — a staggering 33.41% of all registered voters.

This nearly tripling of the 26-35 cohort (from 2.2 million to 6.6 million) was the single biggest demographic shift in Kenya's electoral history between those two cycles.

From Voters to Candidates: The 3,428 Who Tried

Being a majority of voters did not translate into equivalent political representation. A total of 3,428 youth candidates ran for elective office in 2017. Here is how they were distributed:

• Presidential: 0 youth candidates
• Gubernatorial: 7 (all male)
• Senatorial: 35 (30 male, 5 female)
• Member of National Assembly: 260 (248 male, 12 female)
• Woman Representative: 35 (all female)
• Member of County Assembly (MCA): 3,091 (2,924 male, 167 female)

The MCA position attracted 90.2% of all youth candidates, which makes sense — it is the most accessible entry point into elective politics, with smaller constituencies and lower campaign costs.

The Harsh Reality: Only 314 Won

Of those 3,428 youth candidates, only 314 won their races. That is an overall success rate of just 9.2%. The breakdown:

• Governors: 1 out of 7 (14.3%)
• Senators: 6 out of 35 (17.1%)
• MPs: 17 out of 260 (6.5%)
• Women Representatives: 3 out of 35 (8.6%)
• MCAs: 287 out of 3,091 (9.3%)

The funnel effect is dramatic. Over ten million youth voters, 3,428 youth candidates, and just 314 winners. The political system is powered by young voters but largely run by older leaders.

The Gender Gap Among Youth Candidates

The gender disparity among youth candidates was stark. Of the 3,428 youth candidates, 3,209 were male (93.6%) and only 219 were female (6.4%). The success rates were even more unequal when analysed by position — a topic we explore in depth in our companion analysis of youth candidate success rates.

What This Means for Kenya's Democracy

The 2017 data reveals a paradox at the heart of Kenyan democracy: the people who make up the majority of voters are dramatically underrepresented among elected leaders. With 51% of registered voters being under 35, Kenya's youth have the raw numbers to reshape the political landscape. But turning voter numbers into electoral victories requires more than just showing up on election day.

It requires campaign funding, party support, name recognition, and the kind of political networks that take years to build. For most young candidates, these remain out of reach.

Understanding these dynamics is exactly what Votrack was built for. By tracking results at the polling station level, campaigns can identify exactly where youth candidates are performing well and where they are losing ground — in real time.
