+# Sea-Coast Development
+
+## Definition
+
+The pattern of economic development that occurs first along coastlines where water-carriage provides access to the widest possible markets. Sea-coast regions historically develop industry, trade, and division of labour before inland areas due to their superior access to extensive markets.
+
+## Source Chapter
+
+Book I, Chapter 3
+
+## Context
+
+Smith argues that improvements in art and industry naturally begin where water-carriage opens the whole world as a market, and only later extend to inland parts of the country. He uses examples from North American colonies and Mediterranean civilizations to demonstrate this developmental pattern.
