Gross domestic product and gross net product
Gross Domestic Product (GDP) is the total monetary value of all goods and services produced within a country's borders in a given period, regardless of who produces them. Gross National Product (GNP) - I think you mean GNP rather than "gross net product" - measures the total output produced by a country's residents/nationals, regardless of where they are located.
The key difference: GDP = production within borders; GNP = production by nationals (wherever they are).

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.

I now have all the exact definitions from Park's textbook. Let me read a few more lines to capture the NNP and NDP definitions as well.
Reading File
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.

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."

Here is the complete information on Suraksha Clinics as per Park's Textbook:
Suraksha Clinics - As per Park's Textbook of Preventive and Social Medicine
Definition / What is a Suraksha Clinic?
"NACO has branded the STI/RTI services as 'Suraksha Clinic', and has developed a communication strategy for generating demand for these services."
In short, Suraksha Clinic is the brand name given by NACO (National AIDS Control Organisation) to the STI/RTI (Sexually Transmitted Infections / Reproductive Tract Infections) service centres across India.
Context and Background
- STD control is linked to HIV/AIDS control because behaviour causing STD transmission and HIV transmission is the same
- HIV is transmitted more easily in the presence of another STD
- Hence, early diagnosis and treatment of STD is a major strategy to control spread of HIV infection
- Services for treatment of RTIs and STDs have been integrated at all levels of health care (Department of Family Welfare + NACO coordination)
Location of Suraksha Clinics (STI/RTI Clinics)
| Level | Role |
|---|---|
| District / Block / FRU level | Function as referral centres for STDs referred from peripheries |
| District hospitals | Strengthened with technical support, equipment, reagents, drugs |
| Medical colleges | Strengthened STD clinics |
Services Provided at Suraksha Clinics
- Syndromic management of STDs/RTIs (treatment based on symptoms/signs - NOT dependent on lab investigations)
- Counselling services
- Provision of good quality condoms to STD patients
- Services of NGOs utilised for counselling
Pre-Packed STI/RTI Colour Coded Kits
Provided free of cost to all designated Suraksha/STI/RTI clinics, procured centrally and supplied via State AIDS Control Societies:
| Kit | Colour | Indication |
|---|---|---|
| Kit 1 | Grey | Urethral discharge, ano-rectal discharge, cervicitis |
| Kit 2 | Green | Vaginitis |
| Kit 3 | White | Genital ulcers |

I now have all the content needed. Here is the complete classification directly from Narayan Reddy:
Classification of Mechanical Asphyxia
As per The Essentials of Forensic Medicine and Toxicology - K.S. Narayan Reddy (36th Edition)
Definition of Asphyxia (Narayan Reddy)
"Asphyxia is a condition caused by interference with respiration, or due to lack of oxygen in respired air, due to which the organs and tissues are deprived of oxygen (together with failure to eliminate CO₂), causing unconsciousness or death. The term asphyxia indicates a mode of dying, rather than a cause of death."
Overall Classification of Asphyxia (7 Types)
Narayan Reddy classifies asphyxia into 7 types, of which Mechanical is Type 1:
| Type | Category |
|---|---|
| 1 | Mechanical |
| 2 | Pathological |
| 3 | Toxic |
| 4 | Environmental |
| 5 | Traumatic |
| 6 | Postural |
| 7 | Iatrogenic |
Classification of MECHANICAL Asphyxia (Type 1) - 5 Subtypes
"In this, the air-passages are blocked mechanically."
Narayan Reddy classifies mechanical asphyxia into 5 subtypes (a-e):
| Subtype | Mechanism | Example |
|---|---|---|
| (a) | Closure of external respiratory orifices - closing nose and mouth with hand/cloth or filling with mud | Smothering |
| (b) | Closure of air-passages by external pressure on the neck | Hanging, Strangulation, Throttling |
| (c) | Closure of air-passages by impact of foreign bodies in larynx or pharynx | Choking |
| (d) | Prevention of entry of air due to air-passages being filled with fluid | Drowning |
| (e) | External compression of chest and abdominal walls interfering with respiratory movements | Traumatic asphyxia |
Pathology of Mechanical Asphyxia (Narayan Reddy)
Compression of Neck mechanism:
"When the neck is compressed, occlusion of jugular veins prevents venous drainage from the head, but the arterial supply continues through the carotid and vertebral arteries. When the air-passages are occluded, the impaired oxygenation in the lungs causes a decrease in the oxygen content of arterial blood. Reduction in oxygen tension causes capillary dilation which is followed by stasis of blood in the dilated capillaries and venules, which produces capillo-venous engorgement. This blood stasis causes congestion of organs, and venous return to the heart is diminished leading to anoxia, which causes capillary dilatation, and the vicious cycle goes on."

The library only has the 36th edition (2026) of Narayan Reddy - the 35th edition is not available in the database.
I can only confirm the page number from what is in our library:
- 36th Edition - Classification of Mechanical Asphyxia: pages 142-143
For the 35th edition, the page number is likely to be the same or very close (page 142-143), as Narayan Reddy editions typically do not shift content drastically between consecutive editions. However, I cannot confirm this with certainty since the 35th edition is not in our textbook library.
To verify the exact page in the 35th edition, I would recommend checking your physical copy directly under Chapter 6: Asphyxia.
