Like many popular high schoolers, manufacturing is very much into itself. The largest supplier to manufacturers is other manufacturers, and the largest user of the industry's products is the industry itself. This may be reflection of the complex supply chains in manufacturing compared to other industries.
Despite the industry's reputation for high-quality employment, labor costs are only the fourth largest input by cost (on the left-hand side). Gross operating surplus, which is the return to capital and owners, is larger than labor costs in this industry. The reason is not low pay—this is the 6th highest paying industry (out of 14) in the economy. But high productivity (output per worker) means that the industry doesn't need to employ many people in order to maintain high levels of production. And manufacturing workers use more capital than workers in most other industries, which translates to a large capital base and the need to pay for it—hence large profits (capital returns) in this industry.
Mining is among the larger sources of inputs. The raw materials produced by mining mostly have to be worked on (in manufacturing) before they become usable. For example, there isn't much use for taconite pellets (raw iron ore) until they are taken to a steel mill and converted into steel products.
Services in this part of the economy (or cafeteria table in the high school, if we want to keep the metaphor going) are a smaller share of inputs than mining and manufacturing together. While services provide the majority of value added and output in the U.S. economy, they are smaller contributors to manufacturing—accounting for about one-third of manufacturing inputs, and a similar share of manufacturing's users.
Uses of manufacturing are concentrated in final demand categories. Almost half of manufacturing output is sold directly to households (personal consumption expenditures), for business investment, to foreigners (exports) or to governments (local, state, or federal). The amount used as inputs by all service industries is slightly less than final demand uses.
The tree map for uses focuses on industries that buy manufacturing products. And, as noted, manufacturing is the largest user of its own products. Construction and transportation are the second largest users of manufacturing inputs. The rest of the services industries and mining split the remainder (25%) of manufacturing output used as intermediate production. Service industries generally aren't as large a market for manufactured goods as final demand or manufacturing itself.
