The 1979 Report That Predicted Seoul's Overcrowding

I tracked down and read a national land-use report from 47 years ago

What should you do when life feels directionless?

A younger friend once asked me that exact question, and I told them to read historical records. Not novels like Romance of the Three Kingdoms, but the dry, fact-by-fact kind of document. I especially recommended official papers written 20 to 30 years ago. Looking at what someone in the past prepared for while gazing toward the future makes where you’re standing right now a little clearer.

So I did it myself. I found and read a document completed in 1979 called “Land Vision for the 2000s” (Gukto Guguang, a national land development blueprint). Its worries about concentration in the Seoul metropolitan area and capital flowing into real estate overlapped almost exactly with the problems we face today.

🔍 A National Roadmap, Typed Out by Hand

It’s 1979, an era when people used typewriters and hand-drawn maps instead of computers. The planning committee of the time set out to predict what South Korea would look like 20 years later, in the 2000s, and drew up a roadmap for how the nation’s land should be used. The document still bears the marks of its era: prose mixing Chinese characters with Hangul, hand-drawn road network maps, even the uneven impressions of typewriter keys. Just from the writing style and the print quality, you can tell exactly what tools were used to make it, and how.

What’s inside this document is still startling to read today.

Let’s start with population density. As of 1976, South Korea’s population density was 358 people/km², among the highest in the world outside places like Singapore and Taiwan. With 37 million people living on 98,800 km² of land, per-capita land area came to just 2,800 m² — narrow compared to Japan’s 3,000 m² and West Germany’s 4,000 m². The report found that over the preceding 18 years (‘61–‘78), economic growth had pushed land productivity per unit area up roughly fivefold, but that this still amounted to only 1/6 of Japan’s level and 1/7 of West Germany’s.

The report took a hard look at how, on this cramped land, population kept concentrating in Seoul. Running through the entire document is a sense of alarm: a city-state-like density was taking hold, but urban infrastructure was in no position to handle it. From this, the report drew three core warnings.

First, overcrowding of the capital region was inevitable. As population and functions concentrated in the greater Seoul metropolitan area, transportation, housing, and education infrastructure would demand astronomical additional spending. The report estimated that each additional resident of Seoul would cost roughly ₩450,000 (~$324) per year (in 1978 prices) in urban infrastructure — spanning housing, transportation, education, public health and sanitation, utilities, and social welfare.

Second, money flowing into real estate would crowd out investment in the future. The report’s logic was straightforward: as people flock to Seoul, land prices rise; as land prices rise, capital chases real estate; and as capital chases real estate, less money is left for technology development or industrial investment. Even in 1979, this trajectory was already being flagged as a warning.

Third, relocating the administrative capital should be actively pursued. Remarkably, the document laid out a concrete plan to move the administrative capital to the center of the country — roughly where present-day Sejong City, South Korea’s purpose-built administrative capital, now sits. The logic was that building up the Daejeon region¹, a metropolitan area in central South Korea, into a core hub of national development was the way to prevent Seoul from becoming overcrowded. The original text reads: “Given current conditions of land use, developing an initial foothold in the Daejeon region is the single most critical task for preventing overcrowding of the Seoul metropolitan area.”

The report went further still, addressing energy. Anticipating that dependence on imported energy resources would reach 95% by the 2000s, it proposed research and development into solar housing, a 50% improvement in heating efficiency through conversion to apartment and row-house housing stock, and aggressive development of alternative energy sources. Half a century ago, this document was already talking about an energy transition.

📊 Later Plans Still Couldn’t Solve Capital-Region Concentration

Twenty years later, in 1999, the 4th Comprehensive National Territorial Plan² (2000–2020) was published. Flip through this document and you can see, in numbers, just how accurate the 1979 report’s warning had been.

According to the 4th plan’s own diagnosis, the capital region—just 11.8% of the nation’s land area—held 45.5% of the population and 55.1% of manufacturers. Over 80% of government-invested institutions and 95% of the headquarters of the top 100 companies were clustered there. Compare that to the capital-region population concentration in other countries at the time—31.9% in Japan, 18.5% in France, 11.8% in the UK—and Korea’s imbalance stands out as extreme.

Concentration along the Gyeongbu axis³ was even more extreme. The Gyeongbu axis’s share of the national population jumped from 43.8% in 1960 to 73.3% in 1995. Over the same period, the Honam region’s share fell from 23.8% to 11.7%, and Gangwon’s from 6.5% to 3.3%. Between 1960 and 1995, the Gyeongbu axis alone absorbed roughly 22 million additional people.

The 4th plan pinpointed the problem accurately, too. It named “the deepening of capital-region concentration and regional imbalance” as the number-one issue, and even admitted, self-critically, that “development-first priorities intensified environmental pollution and damage to nature.” It also diagnosed a lack of enforcement power in national territorial planning. Going further, it presented figures showing logistics costs at 16.5% of GDP (₩69.6 trillion (~$50.1 billion), 1997) and traffic congestion costs at 4.4% of GDP (₩18 trillion (~$13 billion)), warning that infrastructure shortages were directly eroding national competitiveness. It also flagged that 70% of total freight volume was concentrated on the Gyeongbu axis.

Then, in 2020, the 5th Comprehensive National Territorial Plan (2020–2040) arrived. This plan was drawn up quite differently: it convened a 170-person citizen participation panel, ran three rounds of deliberation, and even operated an online platform. It set out the vision of “A Territory for Everyone, a Place to Live Together,” proposing three directions: a balanced territory, a smart territory, and a vibrant territory.

And yet, in 2020—the very year this 5th plan was announced—the capital region’s population surpassed the rest of the country’s for the first time. As of 2022, the capital region’s population share stood at 50.5%, roughly 26.05 million people. The total fertility rate had already fallen below 1 for the first time ever in 2018, at 0.98. The capital-region concentration the 1979 report warned about remained an unsolved problem in every plan that followed.

🧩 Why Couldn’t We Solve a Problem Everyone Knew About?

Lay the three documents side by side, and the same problem keeps resurfacing. In 1979, in 1999, and again in 2020, overcrowding in the Seoul metropolitan area was flagged as the issue. Relocating the administrative capital came up repeatedly too, starting in 1979. The Roh Moo-hyun administration tried to actually carry it out, but political and vested interests reduced it to a partial relocation.

Reading through the National Territorial Comprehensive Plans from the 1st to the 5th in sequence, at some point the direction the plans offer stops being clear. I don’t think this is the fault of any particular administration — rather, I think it’s because the priorities placed ahead of the plan kept shifting.

The 1st plan (1972–1981) was unambiguous: build infrastructure for economic growth. They laid highways and built the southeastern coastal industrial belt. They divided the country into four major river-basin development zones and connected the entire territory into a single-day living zone with 1,225km of expressways. There was one goal, and execution followed. Of course, this period also planted the seeds of side effects like metropolitan overcrowding and the urban-rural divide — but at least the direction was clear.

Even by the 4th plan (2000–2020), concrete, high-intensity alternatives were still alive — capital relocation, preventing overcrowding, restructuring the real-estate-driven economy. It laid out specific directions too, like shaping the national territory for the information age and positioning Korea as a hub for Northeast Asian exchange. But as vested interests clashed and collided along the way, the plan gradually turned into a “document that inconveniences no one much, and looks good on paper.”

You can feel that shift when you read the “National Territorial Planning Charter” in the 5th plan. “Guarantee a minimum quality of life and opportunity regardless of where one lives,” “a clean and beautiful national territory,” “distinctive and attractive spaces.” Who could possibly object to any of that? But I felt that goals like these alone don’t make clear who should act, and on what, first.

The 1979 report, by contrast, spelled out uncomfortable sentences directly: phrases like “this is expected to further intensify Seoul’s overcrowding” and “as this is the single most critical task, it must be actively pursued.” The tone pointed at a direction, assigned responsibility, and demanded action. As time went on, that sharpness disappeared.

What’s interesting is that the 1979 report didn’t stop at simple warnings — it laid out concrete alternatives. It proposed cutting heating energy use by shifting to apartments and row houses, and it analyzed that distributing educational facilities evenly across regions was a way to directly address the root cause of Seoul’s overcrowding. You can see an attempt to tackle the problem on multiple levels at once. The 5th plan did propose regional linkage and cooperation projects, but most came with the caveat “not yet developed into a concrete planning stage.” In the meantime, the plan’s alternatives actually became less concrete, not more.

The draft looks accurate and complete. No corrections needed.

Oswarld’s Lens

I once had a chance to video call with a few people based in the Bay Area. The conversation naturally started with AI, but that topic didn’t last long. They mentioned the next-generation model was already built internally and had already finished testing. The agenda there had already shifted to A2A (AI to Action)—that is, how AI would actually exert physical influence on the real world. The conversation moved on to education, biology, even materials engineering.

After the meeting, I had a strange feeling. It was like I’d just come back from 10 years in the future. We’re still at the stage of talking about the AI models themselves, while they were already discussing how to apply the technology to fields like education, biology, and materials engineering.

There’s something I learned while building GTM strategy. A good strategy has to pick a direction that’s uncomfortable for someone. A sentence everyone agrees with doesn’t tell you what to actually do—it’s closer to a declaration than a strategy. The 1979 national land plan worked not just because of the ruling regime’s power at the time, but because it contained a clear philosophy and an uncomfortable sense of direction.

In the end, the lesson left by that report from 47 years ago is a single one. Even if you gather the smartest experts in the world to produce a perfect diagnosis, turning it into execution requires someone’s philosophy and sense of autonomous responsibility. Whether that’s a nation, a company, or an individual life.

Closing

Even now, that typewritten report from 47 years ago still holds up. Overcrowding in the Seoul metropolitan area, capital flowing into real estate, population drain from the regions—various plans offered alternatives, but these problems remain unsolved to this day.

And this isn’t just a story about the past. We’re standing at another such crossroads again. Looking back leaves us with regret, and looking ahead brings worry. So I think the answer is to focus on what I can do right now.

If reading old official documents or national plans has ever changed how you see today’s problems, let me know in the comments.
