<h4 class="notes-h4">What Is Population?</h4>
<p><strong>Population</strong> refers to the total number of people living in a given area at a particular time.</p>
<p><strong>Population distribution</strong> refers to how people are spread across a geographical area — whether evenly or unevenly.</p>
<p><strong>Population density</strong> = Total population ÷ Total land area (in km²)</p>
<ul class="notes-list">
<li>Expressed as: <strong>persons per km²</strong></li>
</ul>
<hr class="section-divider">
<h4 class="notes-h4">Population Distribution in Africa</h4>
<p>Africa is the second largest continent and the second most populous in the world. However, population is very <strong>unevenly distributed</strong>.</p>
<p><strong>Densely populated areas (many people):</strong></p>
<ul class="notes-list">
<li>Nile Delta and Nile Valley (Egypt, Sudan) — fertile land and water</li>
<li>West African coast (Nigeria, Ghana, Côte d'Ivoire) — fertile land, trade, resources</li>
<li>East African highlands (Kenya, Ethiopia, Uganda) — cool, fertile land, reliable rainfall</li>
<li>South African eastern coast — economic development and industry</li>
</ul>
<p><strong>Sparsely populated areas (few people):</strong></p>
<ul class="notes-list">
<li>Sahara Desert (North Africa) — harsh climate, lack of water</li>
<li>Kalahari Desert (Southern Africa) — dry conditions</li>
<li>Congo Basin rainforest — dense vegetation, diseases (malaria, sleeping sickness)</li>
<li>Namib Desert (Namibia/Angola) — arid conditions</li>
</ul>

<h4 class="notes-h4">Population in Kenya</h4>
<p>Kenya's population is approximately <strong>55 million</strong> (2024 estimate).</p>
<p><strong>Densely populated areas:</strong></p>
<ul class="notes-list">
<li>Central Highlands (Kiambu, Muranga, Nyeri) — fertile volcanic soils, tea and coffee farming</li>
<li>Western Kenya (Kisumu, Kakamega, Kisii) — fertile land, high rainfall, near Lake Victoria</li>
<li>Nairobi and its environs — urban employment and services</li>
<li>Coastal strip around Mombasa — trade, fishing, tourism</li>
</ul>
<p><strong>Sparsely populated areas:</strong></p>
<ul class="notes-list">
<li>Northern Kenya (Turkana, Marsabit, Mandera) — arid and semi-arid land, pastoralism</li>
<li>Tsavo region — national park, wildlife, tsetse flies</li>
<li>High altitude areas (Mt Kenya summit) — too cold for settlement</li>
</ul>
<hr class="section-divider">
<h4 class="notes-h4">Population Data — How It Is Collected</h4>
<p><strong>Census:</strong> An official count of all persons in a country at a specific time.</p>
<ul class="notes-list">
<li>Kenya conducts a national census every 10 years (last in 2019)</li>
<li>Collects data on: age, sex, occupation, education, religion, location</li>
<li>Used for: planning schools, hospitals, infrastructure; allocation of resources</li>
</ul>
<p><strong>Methods of presenting population data:</strong></p>
<ul class="notes-list">
<li><strong>Line graphs</strong> — show population growth over time</li>
<li><strong>Bar graphs</strong> — compare populations of different countries or regions</li>
<li><strong>Choropleth maps</strong> — use shading to show density variation</li>
<li><strong>Dot maps</strong> — each dot represents a set number of people</li>
<li><strong>Population pyramids</strong> — show age and sex structure of a population</li>
</ul>
<p><strong>Reading a population pyramid:</strong></p>
<ul class="notes-list">
<li>Y-axis: age groups (0–4, 5–9 … 80+)</li>
<li>X-axis: percentage of population (left = males, right = females)</li>
<li><strong>Broad base, narrow top</strong> → young, rapidly growing population (typical of developing countries, Kenya)</li>
<li><strong>Narrow base, broad middle</strong> → ageing population, slow growth (typical of developed countries)</li>

<h4 class="notes-h4">Major Physical Features of East Africa</h4>
<p><strong>1. The Great Rift Valley</strong></p>
<p>The East African Rift System is one of the world's most significant geographical features — a series of valleys, escarpments, volcanoes, and lakes formed by the pulling apart (rifting) of the African tectonic plate.</p>
<p><strong>Formation:</strong></p>
<ol class="notes-list">
<li>Two sections of the Earth's crust (tectonic plates) began pulling apart millions of years ago</li>
<li>The land between them sank (subsided) — forming the rift valley floor</li>
<li>The edges became steep escarpments</li>
<li>Volcanic activity along the rift created volcanoes and crater lakes</li>
</ol>
<p><strong>Features of the Rift Valley:</strong></p>
<ul class="notes-list">
<li><strong>Escarpments</strong> — steep walls on either side (e.g., Mau Escarpment, Nyandarua/Aberdare escarpment)</li>
<li><strong>Rift valley floor</strong> — lower land in the middle</li>
<li><strong>Volcanoes</strong> — Mt Longonot, Mt Suswa, Mt Elgon (Kenya), Mt Kilimanjaro (Tanzania)</li>
<li><strong>Rift valley lakes</strong> — Turkana, Baringo, Bogoria, Nakuru, Elementaita, Naivasha, Magadi (Kenya); Tanganyika (deepest in Africa), Malawi/Nyasa</li>
</ul>
<p><strong>Importance of the Rift Valley:</strong></p>
<ul class="notes-list">
<li>Rift valley lakes support fishing, tourism, flamingos (Bogoria, Nakuru)</li>
<li>Geothermal energy (Olkaria Geothermal Plant near Naivasha)</li>
