Traveling in steerage, the cheapest class on transatlantic ships, exposed passengers to overcrowding, malnutrition, and deadly infectious disease. For millions of immigrants in the 19th and early 20th centuries, the price of a new life was weeks spent in conditions that could permanently damage their health or kill them before they ever reached shore. In 1847 alone, 17,465 people died during or shortly after transatlantic voyages, most of them steerage passengers.
Overcrowding and Living Conditions
Steerage occupied the lowest deck of the ship, typically with ceilings only six to eight feet high. Passengers slept in rows of wooden bunks stacked so tightly that advertisements actually boasted when there was enough room for an adult to sit up in bed. Hundreds of people shared a single open compartment with little ventilation, no privacy, and almost no access to fresh air or daylight. The space doubled as sleeping quarters, dining area, and living room for the entire voyage, which could last anywhere from two weeks to over a month depending on weather and the era of travel.
This density created conditions that were miserable even on a good day. The air below deck was thick with the smell of unwashed bodies, seasickness, and waste. Rough seas made things worse: passengers who were too sick to climb to the upper deck had no choice but to stay in their bunks, surrounded by others in the same condition. There was no system for cleaning the space during the voyage, and bedding often became infested with lice.
Disease Was the Deadliest Consequence
The combination of close quarters, poor sanitation, and contaminated water made steerage a breeding ground for infectious disease. Typhus, sometimes called “ship fever,” was the most common killer. It spread through body lice, which thrived in the crowded, unwashed conditions below deck. Cholera, smallpox, and dysentery also swept through steerage compartments regularly.
The mortality numbers were staggering. On one sailing of the ship Marchioness of Abercorn, 140 out of 400 passengers died, most from typhus. That is a 35 percent death rate for a single crossing. Cholera spread through the contaminated drinking water passengers shared, and dysentery, a severe intestinal infection causing painful cramping and dehydration, could move through an entire compartment in days. Once disease broke out, there was essentially no medical care available and nowhere to isolate the sick from the healthy. Passengers who boarded in good health could be gravely ill within a week.
Ships carrying Irish emigrants during the famine years of the 1840s earned the name “coffin ships” for good reason. The combination of passengers who were already weakened by hunger and the brutal conditions in steerage produced death tolls that shocked even contemporaries.
Malnutrition Over Weeks at Sea
Steerage passengers received basic weekly rations, not meals. The diet consisted mainly of salted meat and hard ship’s biscuits, supplemented with oatmeal, dried peas, raisins, and treacle. There was no fresh fruit, no vegetables, and no refrigeration. Passengers were often expected to cook their own food using shared facilities on deck, which became impossible in bad weather.
Weeks of this diet left passengers malnourished and more vulnerable to the diseases circulating around them. Those who boarded already in poor health, as many famine-era Irish emigrants were, had little nutritional reserve to fight off infection. Dehydration compounded the problem, since the water supply on board was limited and frequently contaminated.
A Different Experience at the Border
The consequences of steerage travel did not end when the ship reached port. In the United States, the immigration system itself treated steerage passengers differently from those who could afford better tickets. When a ship arrived in New York Harbor, first- and second-class passengers were examined by medical officers on board the ship as it sailed up the harbor. If they passed inspection, they disembarked directly at the dock.
Steerage passengers had no such convenience. They were transferred by barge to Ellis Island, where they faced a separate, more rigorous screening process. Doctors watched them climb stairs, looking for signs of heart or lung problems. They checked eyes for trachoma, a contagious infection that was grounds for deportation. Anyone flagged with a suspected illness could be detained on the island for days or weeks, and those deemed too sick or likely to become a public burden were sent back on the next ship. After enduring weeks of dangerous conditions that made illness more likely, steerage passengers then faced a system designed to reject them for being ill.
Lasting Effects on Survivors
Even passengers who arrived without obvious disease often carried lasting consequences. Weeks of malnutrition, dehydration, and exposure to infections weakened immune systems. Typhus survivors could experience lingering fatigue and complications for months. Those who contracted dysentery or cholera during the voyage sometimes arrived too debilitated to work immediately, putting them at an economic disadvantage in their new country from day one.
The psychological toll was real as well. Many passengers watched family members or fellow travelers die during the crossing, with bodies buried at sea. The trauma of weeks in dark, filthy, disease-ridden conditions, combined with the uncertainty of what awaited at port, shaped how immigrants experienced their first chapter in a new country. For the millions who passed through steerage, the crossing itself was one of the most dangerous parts of the journey.
