Does Household final consumption Expenditure include Consumption expenditure of Imported Goods From World Bank, I got the Household final consumption Expenditure for many countries across time. I wonder if this consumption includes Consumption expenditure of Imported Goods / Import Volume?

If I want to compute the share of consumption of home goods in total consumption, should I use the following formula?

$\frac{Household final consumption Expenditure - Import Volume}{Household final consumption Expenditure}$

or should I use:

$\frac{Household final consumption Expenditure}{Household final consumption Expenditure + Import Volume}$

Many thanks for your help.
Yes.

Household final consumption expenditure consists of the expenditure, including expenditure whose value must be estimated indirectly, incurred by resident households on individual consumption goods and services, including those sold at prices that are not economically significant and including consumption goods and services acquired abroad.
(From System of National Accounts, 2008, p. 623, PDF).

To elaborate, in the familiar identity $$Y = C + I + G + (X - M),$$ the reason we subtract $M$ (imports) is that the terms $C$, $I$, and $G$ also include imported goods and services.
In particular and to your secondary question, let:

$C_d =$ Consumption of domestically-produced goods and services.
$C_m =$ Consumption of foreign-produced goods and services.

Then: $$C=C_d+C_m.$$
And what I believe you want is $\frac{C_d}{C}$ or equivalently $1-\frac{Cm}{C}$.
