Agricultural Density: Formula, Egypt and US Worked Numbers

Agricultural density is the number of farmers divided by the area of arable land they work. On World Bank and ILO-modelled figures for 2024, Egypt has about 181 farm workers per square kilometre of arable ground, or one worker for every 1.4 acres. The United States has 1.7, or one worker for every 143 acres.

That gap of about 105 times is why the measure is useful. It tells you how much farm work rests on people and how much on machines. This page gives the formula, works the numbers for Egypt and the US, compares 10 countries, and has a calculator for your own figures.

One warning before you copy a number into an assignment or a report. You may see a figure of about 3,500 per km² given for Egypt as if it were agricultural density. It is close to Egypt’s physiological density, which counts all people, not just farm workers. The two are easy to mix up, so both are worked out below from the same data.

Three density measures compared

All figures are our calculations from World Bank data for 2024. Read across a row and the same country changes character. Egypt is about 3 times as crowded as the US by arithmetic density, 16 times by physiological density and 105 times by the farming measure. The measure you pick decides the story you tell.

The agricultural density formula

The formula is short:

Agricultural density = number of farmers ÷ area of arable land

The US Census Bureau’s geography lesson on density describes the usual method the same way: population of farmers over arable land. That lesson uses the number of farms in place of farmers because of the data it has, which is a fair swap if you say you made it. The other two density measures use the same shape and change what goes above or below the line.

• Arithmetic density = total population ÷ total land area. It shows how crowded a country is and says nothing about farming.
• Physiological density = total population ÷ arable land. It shows how many people each farmable square kilometre would have to feed if a country fed itself.
• Agricultural density = farmers ÷ arable land. It measures how much labour the farm system uses for each unit of land.

What agricultural density measures, and why it is useful

It measures labour per unit of farmable land. A high number points to small plots and hand work. A low number points to large farms, machinery and few workers. That makes it useful for comparing farm systems, and for seeing how a country changes as workers leave the land. It does not tell you how much food a country grows or how well it farms.

What counts as arable land

The bottom of the fraction matters as much as the top. The World Bank arable land series uses the FAO definition: land under temporary crops, temporary meadows, market or kitchen gardens and land temporarily fallow. Double-cropped land is counted once.

That last rule matters a lot for Egypt, where much of the land carries more than one crop a year. An FAO country paper on Egypt gives an older, undated cropping ratio of about 2:1, and FAO’s AQUASTAT profile gives an irrigated cropping intensity of 176% for 2002. If you divide by cropped area instead of arable land, your answer can fall by nearly half. Say which one you used.

What counts as a farmer

No global register of farmers exists, so the top of the fraction needs a method. Every country figure on this page uses the same three steps: take the labour force, remove the unemployed, then multiply by the share of jobs in farming. The share comes from the World Bank employment in agriculture series, which holds modelled ILO estimates.

That series covers agriculture, hunting, forestry and fishing, and it counts hired workers as well as owners. So it can run higher than a count of farm owners. For a wider view of how farm labour and population are shifting, see our overview of agricultural population density.

Four checks before you use a density figure

1. Date each input. Land and labour series do not always end in the same year. All country figures here use 2024.
2. Turn it upside down. 181 workers per km² works out to 1.4 acres per worker. If the result looks absurd, the density is wrong.
3. Name the land measure. Arable, cropped or agricultural land give different answers. Egypt’s agricultural land, which adds permanent crops and pasture, was 4.25% of its land area in 2024, against 3.3% for arable land.
4. Check the top number against a second source. The US section below does this with USDA census data.

Agricultural density of Egypt, step by step

Here is the full sum for Egypt, so you can update any input when new data comes out. All inputs are for 2024 and come from the World Bank.

• Arable land: 3,274,000 hectares, which is 32,740 km² or about 8.09 million acres.
• Total land area: 995,450 km². Arable land is 3.3% of the country.
• Population: 116,538,258.
• Labour force: 35,343,331, with unemployment at 6.82%.
• Share of jobs in agriculture: 17.98%, which gives about 5.92 million farm workers.

Those inputs give three results for Egypt:

• Arithmetic density: 116,538,258 ÷ 995,450 = 117 people per km².
• Physiological density: 116,538,258 ÷ 32,740 = 3,560 people per arable km².
• Agricultural density: 5.92 million ÷ 32,740 = 181 workers per arable km².

Egypt’s physiological density is about 20 times its farming density because about 82% of working Egyptians do something other than farm, and everyone in the country counts in the population figure.

Egypt’s arable land percentage has moved, and so has the answer

Older pages quote different numbers for a simple reason: the land series changes and gets revised. It reached 3,365,000 hectares in 2020, dropped to 3,078,000 in 2021, then climbed to 3,274,000 in 2024. Land reclamation adds area, and building on farmland takes it away. AQUASTAT calls farmland urbanization a serious threat to Egyptian farming. Meanwhile the population grew by about 2 million a year between 2023 and 2025.

How many farmers Egypt has

About 5.9 million people worked in agriculture, forestry and fishing in Egypt in 2024, on the method above. The farm share of jobs is falling, from 26.0% in 2015 to 17.5% in 2025 on the modelled series, though much of that is one jump, from 25.1% in 2017 to 21.7% in 2018, so treat the trend with care. So the density can fall even when the land area stays the same. The sector produced 13.7% of GDP in 2024, against 18% of jobs.

US agricultural density, and how to work it out by state

Here is the national sum for 2024. Arable land was 151,553,420 hectares, which is 1,515,534 km² or about 374.5 million acres. The labour force was 174.2 million, unemployment 4.02% and the farm share of jobs 1.57%. That gives about 2.62 million workers, 1.73 per arable km², or one per 143 acres.

USDA data gives a useful check. The 2022 Census of Agriculture counted 3,374,044 producers, 1,900,487 farms and 382.4 million acres of cropland. That is one producer per 113 acres of cropland, or one farm per 201 acres. The worker-based figure of 143 acres sits between them, which is about as close as this measure gets. The methods differ: the census records up to four producers per farm, while the World Bank series also counts hired workers, forestry and fishing.

The trend is toward fewer farms. USDA’s Farms and Land in Farms summary (February 2026) estimated 1,865,000 farms and 873.95 million acres in 2025, with an average of 469 acres. These are estimates of all land in farms, including pasture, so do not use them as a cropland figure.

Four steps for a state or county

1. Open USDA NASS Quick Stats and choose the Census of Agriculture for one census year.
2. Pull the number of farm operations and the cropland acres for your state or county.
3. Divide operations by cropland acres.
4. Multiply by 247.1 to get farms per km², or by 640 to get farms per square mile.

For the whole US in 2022, that sum gives 1.23 farms per km² of cropland. A farm count is lower than a worker count, so never compare this figure directly with the 1.73 above. The census runs every five years, so county figures change on that cycle.

Countries with low agricultural density

Low agricultural density means few farm workers spread over a lot of farmable land. Among the countries worked here, Canada is lowest at 0.63 per km², with 392 acres per worker. Australia follows at 1.0 and the US at 1.7. Each of these has a large area of arable land compared with its farm workforce.

The low figure usually comes with three things:

• Machinery in place of labour. Large equipment covers land that would otherwise need many hands.
• Larger farms. US farms averaged 466 acres in 2024 and 469 in 2025, while farm numbers kept falling, on USDA estimates.
• Distance. One worker with hundreds of acres cannot walk all of them each week. Satellite maps are one way to choose which fields to check first.

Why the measure can mislead

New Zealand shows the weakness. It has 30.9 workers per arable km², far above the US, though its farm sector is not labour-heavy in the way Egypt’s is. Its arable area is just 5,220 km², about 2% of its land, and a measure based on arable land leaves out pasture. So livestock countries look more crowded than they are. If a country relies on grazing, compare it on agricultural land as well.

Physiological density: Egypt and South Korea

A common class question compares these two countries. It says Egypt has more land and more farmers than South Korea, but a higher physiological density. Check the premise against current data. On World Bank figures for 2024, South Korea had 51.75 million people on 13,020 km² of arable land, or 3,975 per km². That is above Egypt’s 3,560. Older data may rank them the other way, so give your year.

The farming measure still separates them. Egypt has 181 workers per km² and South Korea 116. Egypt also has more farm workers, at about 5.9 million against 1.5 million, and more arable land. Yet neither figure alone says whether a country can feed itself. Physiological density leaves out yields, multiple cropping and food imports. A fair answer says that the country with more arable land has more room to grow food, then checks those three factors.

Does a high agricultural density cost yield?

Not on these figures. Egypt uses about 105 times the labour per unit of arable land of the US, yet its 2024 cereal yield of 7,360 kg per hectare was about 13% below the US figure of 8,414 kg, according to the World Bank cereal yield series. Canada, with the lowest density in the chart, produced 4,021 kg, and Australia 2,690 kg.

Climate and water are likely part of the reason. FAO notes that Egypt’s crop area is irrigated except for some rain-fed land on the Mediterranean coast. Yields also swing from year to year: the Netherlands fell from 8,080 kg in 2023 to 6,806 kg in 2024. So the measure shows how land is farmed, not how well. Treat it as a labour figure, not a yield forecast.

Feddans, acres and land prices

Egyptian farm statistics often use the feddan, so convert before you build a density from an Egyptian source. FAO uses 1 feddan = 0.42 hectares, which is 4,200 m² or 1.038 acres. That older, undated paper also records an average farm unit of 2.5 feddans. Egypt’s 3,274,000 hectares of arable land is about 7.8 million feddans, or about 1.3 feddans per farm worker.

For land prices, treat a broker’s price per feddan as an asking price, not a national average. Old Nile Valley land and newly reclaimed desert are different products, and a dollar conversion moves with the exchange rate. To compare, divide the price per feddan by 1.038 to get a price per acre, then record the date and exchange rate you used. Get local legal and valuation advice before any purchase.

On the US side, USDA’s Economic Research Service puts average cropland value at US$6,020 per acre in 2026 for the 48 contiguous states. That is a national survey-based average, not a list price. State maps are on the NASS land values charts page.

Why Egypt’s density is so high

Geography does most of the work. FAO describes farmland confined to the Nile Valley and Delta, with a few oases and some arable land in Sinai, while rainfall in the Delta is just 25 to 60 mm a year. People and farms sit where the water is. Farming there has deep roots, as our piece on what ancient Egyptians grew explains.

Today, three responses compete. Desert reclamation adds land, and a 1993 water policy described by AQUASTAT aimed to add 1.4 million feddans to the farmed area. Double cropping gets more from existing fields. Protected and urban growing uses little land at all, on the same logic as rooftop farms in Montreal, though at a far smaller scale.

Measuring cropped area from orbit

Every density here depends on a land figure that national statistics update once a year at best. Satellite images update much more often, and they can show which fields carried a crop in a given season. That helps most where double cropping makes annual arable figures hard to read. Farmonaut provides satellite vegetation maps for fields a user draws, so a farm manager can check a boundary through the season without walking it.

FAQ

What is Egypt’s agricultural density?

About 181 farm workers per arable km² for 2024, based on World Bank labour and land data. That is 1.4 acres, or about 1.3 feddans, per worker.

What is Egypt’s physiological density?

About 3,560 people per arable km² for 2024 (116,538,258 people ÷ 32,740 km²). Do not confuse it with the farming measure, which is about 20 times smaller.

What is Egypt’s arithmetic density?

About 117 people per km² for 2024 (116,538,258 people ÷ 995,450 km² of land). Most Egyptians live on a small part of that area, so this number understates crowding along the Nile.

What is the population of Egypt?

The World Bank gives 116,538,258 for 2024 and 118,365,995 for 2025. Egypt’s statistics agency runs a CAPMAS population clock, and the UN World Population Prospects gives estimates and projections. Sources differ, so name the one you use and its date.

How do I calculate agricultural density?

Divide farm workers by arable land in the same area and year. For example, 500,000 workers on 20,000 km² gives 25 per km². Use the calculator above, the World Bank series for countries, and USDA Quick Stats for US states and counties.

What is the agricultural density of the US?

About 1.7 workers per arable km² for 2024, or one worker per 143 acres. Using 2022 census producers and cropland gives one producer per 113 acres.

The one thing to take away

Agricultural density is a ratio of labour to land. It means something only when the land measure, the year and the worker definition come with it. Egypt at 181 and the US at 1.7 show two farm systems that work in opposite ways, one with many people and one with many machines. Run your own figures through the calculator and write down the year of each input.
