How could you partition Household Food Expenditures into Producing Industries?

# How could you partition Household Food Expenditures into Producing Industries?

(Asked by: username_0 on 2021-09-25)

From the [2019 Consumer Expenditure Survey](https://www.bls.gov/opub/reports/consumer-expenditures/2019/home.htm), the average household annual food expenditure was $8,169 for that year. There are subcategories such as "Food at Home" and "Food away from Home," but for simplicity, I'll keep the scope to annual household food expenditures.

I want to partition this $8,169 into the [BEA industries](https://apps.bea.gov/iTable/iTable.cfm?5205=sum&5206=10&isuri=1&reqid=52&step=102#5205=sum&5206=10&isuri=1&reqid=52&step=102) (aggregation level is "summary") for the ultimate goal of assessing pollution impact. That is, if buying bread is related to a farm purchasing harvesting equipment, maybe some of those dollars should be allocated towards both farms and industrial machinery.

Here are a few immediately relevant BEA industry summaries:

* 111CA: Farms
* 113FF: Forestry, Fishing & Related activity (the fish is sold to markets?)
* 311FT: Food and Beverage & tobacco
* 445: Food and Beverage Stores
* 722: Food services and Drinking places

In my studies of the Leontief Input/Output model, one thought is just to pile all $8,169 into 311FT and let the "recipe" tell me how much that 111CA contributed, but that feels contradictory since it predicts 0 final demand at the household level for 111CA, when clearly that industry has a large GDP number.

So what is the best way to "attribute" the household expenditures on food into those industries?

You should try to avoid mixing data sets unless you have a good way to bridge them. There are very precise methodologies used to construct each data set and mixing them can lead to nonobvious problems. You might consider looking at the [BEA's IO tables at a more disaggregated level](https://www.bea.gov/industry/input-output-accounts-data). For example, the Use table shows Personal Consumption Expenditures at a granularity that you might be interested in. For example, in the screenshot below it shows that in 2012, households consumed \$32 billion worth of goods from the "Vegetable and melon farming" product category.
