GDP vs GNP difference explained economics

Here is a clear breakdown of both concepts:

Gross Domestic Product (GDP)

Definition: The total market value of all finished goods and services produced within a country's borders during a specific time period (usually a quarter or year), regardless of who produces them.

A Toyota factory in the US contributes to US GDP
A US company's factory in Mexico does NOT contribute to US GDP

How GDP is Measured

Three approaches give the same result:

Approach	Formula
Expenditure	GDP = C + I + G + (X - M)
Income	GDP = Wages + Rent + Interest + Profit
Production	Sum of value added at each production stage

Where:

C = Consumer spending
I = Business investment
G = Government spending
X - M = Exports minus Imports (net exports)

Types of GDP

Nominal GDP - Measured at current prices (not adjusted for inflation)
Real GDP - Adjusted for inflation; better for comparing growth over time
GDP per capita - GDP divided by population; measures living standards

Gross National Product (GNP)

Definition: The total market value of all goods and services produced by a country's residents/nationals, wherever they are located in the world.

A US citizen working and earning in Germany contributes to US GNP
A German citizen working in the US does NOT contribute to US GNP

The Key Formula Linking GDP and GNP

GNP = GDP + Net Factor Income from Abroad (NFIA)

Where:

NFIA = Factor income earned by residents abroad - Factor income earned by foreigners domestically

If NFIA is positive, GNP > GDP (country's nationals earn more abroad than foreigners earn domestically).

GDP vs. GNP - Side-by-Side Comparison

Feature	GDP	GNP
Focus	Where production happens	Who does the producing
Scope	Within national borders	By nationals, worldwide
Foreign workers	Included	Excluded
Nationals abroad	Excluded	Included
Primary use	Measuring economic output of a territory	Measuring economic welfare of a nation's people
Usage today	More widely used globally	Still used; US reports both

Practical Examples

India has a large diaspora sending remittances home - India's GNP tends to be higher than GDP because Indian nationals earn significant income abroad.
Luxembourg has many foreign workers - its GDP is higher than GNP because foreigners working there boost domestic production but take earnings home.

Related Concepts

Net National Product (NNP) = GNP - Depreciation (capital consumption)
Gross National Income (GNI) = essentially the modern equivalent of GNP; used by the World Bank to classify countries by income level
GDP Deflator = tool to convert nominal GDP to real GDP

The Investopedia GDP vs GNP explainer and Marketplace's breakdown are good supplementary reads.

In short: GDP = production where you are; GNP = production by who you are. Most countries and international organizations (IMF, World Bank) now prefer GDP as the standard measure, but GNP/GNI remains useful when analyzing the economic well-being of a country's citizens across borders.

Here are the exact definitions directly from Park's Textbook of Preventive and Social Medicine (under the chapter "Economic Levels - National Income"):

Definitions as per Park's Textbook

Gross National Income (GNI) / Gross National Product (GNP)

"Formerly known as GNP or Gross National Product. It is gross income generated from within the country as also net income received from abroad. It is expressed either 'at current prices' i.e., at prices prevailing during the period to which the figure refers, or 'at constant prices'; i.e., at prices prevailing during a fixed base period in the past, irrespective of the period to which the figures refers. Thus figures 'at constant prices' discount the effect of inflation after the base period and measure the changes in real terms."

Park also notes that for GNI per capita (US $), the national currency is converted using the World Bank Atlas Method - a 3-year average of exchange rates.

Gross Domestic Product (GDP)

"GDP is gross income generated within a country, i.e., it excludes net income received from abroad."

Net National Product (NNP)

"It is the GNP minus the capital we consume (e.g., equipment, machinery, etc.) in the production process. In other words, NNP is the market value of all final goods and services after providing for depreciation."

Net Domestic Product (NDP)

"It is the gross domestic product minus the value of depreciation on fixed assets."

Additional Definitions from Park

Term	Park's Definition
GDP at Market Price	GDP at factor cost + indirect taxes - subsidies
NNP at Market Price	NNP at factor cost + indirect taxes - subsidies
GNP at Market Price	GNP at factor cost + indirect taxes - subsidies

Park's Context Note

Park further states:

"These aggregates measure the total volume of national economic activity at current or constant price. By dividing the GNP or GDP by the total population, one arrives at per capita GNP or GDP, which are common general purpose indicators of national wealth. Per capita GNP may thus serve as a general measure of human welfare - that is, of health in a very broad sense."

Note on terminology: Park uses the term "Gross Net Product" is not a standard term - Park's textbook uses GNP (Gross National Product), now officially renamed GNI (Gross National Income) by the World Bank. The "net" equivalents are NNP (national) and NDP (domestic), which subtract depreciation from their gross counterparts.

Here is a summary comparison table based directly on Park's Textbook of Preventive and Social Medicine:

GDP vs GNP/GNI - Summary Comparison Table

As per Park's Textbook of Preventive and Social Medicine

Feature	GDP (Gross Domestic Product)	GNP / GNI (Gross National Product / Gross National Income)
Park's Definition	"Gross income generated within a country"	"Gross income generated from within the country as also net income received from abroad"
Income from abroad	Excluded	Included
Scope	Within the country's borders only	Within the country + net foreign income
Modern name	GDP (unchanged)	Now called GNI (formerly GNP) - per World Bank
Expression	At current prices or constant prices	At current prices or constant prices
Inflation adjustment	Figures at constant prices discount inflation	Figures at constant prices discount inflation
Per capita form	Per capita GDP - indicator of national wealth	Per capita GNI (US $) - converted via World Bank Atlas Method (3-year average exchange rate)
Net equivalent	NDP = GDP - depreciation on fixed assets	NNP = GNP - capital consumed in production (depreciation)
At market price	GDP at factor cost + indirect taxes - subsidies	GNP at factor cost + indirect taxes - subsidies
Use in health	Correlated with many health variables	Per capita GNP/GDP = "general measure of human welfare - that is, of health in a very broad sense"

Key Relationship (from Park)

GNI (GNP) = GDP + Net income received from abroad

NDP = GDP - Depreciation on fixed assets
NNP = GNP - Capital consumed in production

Park's Health Context

Park places these definitions under "Economic Levels" in the chapter on social determinants of health, noting:

"Countries with a high per capita GNP are predominantly industrially developed, while those with a low one are predominantly agricultural, or developing."

I now have all the content needed. Here is the complete answer directly from Park's textbook:

First Referral Units (FRU) - As per Park's Textbook of Preventive and Social Medicine

What is an FRU?

A First Referral Unit (FRU) is a health facility (typically a Community Health Centre / CHC at the sub-district level) operationalized to provide emergency and essential obstetric care (EmOC). It serves as the first point of referral from Primary Health Centres (PHCs).

"It has been decided that all the First Referral Units be made operational for providing emergency and essential obstetric care during the second phase of RCH."

Minimum Services of a Fully Functional FRU

24-hour delivery services including normal and assisted deliveries
Emergency obstetric care including surgical interventions like caesarean sections
New-born care
Emergency care of sick children
Full range of family planning services including laparoscopic services
Safe abortion services
Treatment of STI/RTI
Blood storage facility
Essential laboratory services
Referral (transport) services

3 Critical Determinants for a Facility to be "Declared" as an FRU

Park specifically states:

"There are three critical determinants of a facility being 'declared' as a FRU. They are: availability of surgical interventions, new-born care and blood storage facility on a 24-hour basis."

#	Critical Determinant
1	Surgical interventions (24 hours)
2	New-born care (24 hours)
3	Blood storage facility (24 hours)

Physical Requirements to Perform Full Range of FRU Functions

Requirement	Details
Bed strength	Minimum 20-30 beds (relaxable to 10-12 in difficult/NE/EAG states)
Operation theatre	Fully functional
Labour room	Fully functional
Newborn care area	Earmarked and equipped in labour room and ward
Laboratory	Functional
Blood storage	Present
Utilities	24-hour water supply and electricity
Waste disposal	Arrangements in place
Transport	Ambulance facility

FRU and CHC Relationship

The CHC (Community Health Centre) functions as the FRU at the sub-district level
CHC is manned by 4 medical specialists (surgeon, physician, gynaecologist, paediatrician) + 21 paramedical staff
Has 30 indoor beds, one OT, X-ray, labour room, and laboratory
Serves as referral centre for 4 PHCs
As of March 2018: 5,624 CHCs functional in India

Strategic Importance (RCH-II)

"The operationalisation of First Referral Unit at sub-district/CHC level for providing EmOC to pregnant women is a crucial strategy of RCH-II, which needs focussed attention."
