Johnson & Johnson is the world's largest and most diverse healthcare firm. Three divisions make up the firm: pharmaceutical, medical devices and diagnostics, and consumer. The drug and device groups represent close to 80% of sales and drive the majority of cash flows for the firm. The drug division focuses on the following therapeutic areas: immunology, oncology, neurology, pulmonary, cardiology, and metabolic diseases. The device segment focuses on orthopedics, surgery tools, vision care, and a few smaller areas. The last segment of consumer focuses on baby care, beauty, oral care, over-the-counter drugs, and women's health. Geographically, just over half of total revenue is generated in the United States.
