India's latitudinal extent is roughly 8°4′N to 37°6′N and longitudinal extent roughly 68°7′E to 97°25′E; the Tropic of Cancer (23°30′N) passes through eight states including Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura and Mizoram.

The Indian Standard Meridian is 82°30′E, passing near Mirzapur (Uttar Pradesh); IST is 5 hours 30 minutes ahead of GMT, and India's east–west spread of about 30° of longitude creates a two-hour apparent time difference between Arunachal Pradesh and Gujarat.

Himalayan rivers are perennial (snow-fed), while peninsular rivers are seasonal (rain-fed); the Ganga, Brahmaputra and Indus are antecedent/young rivers with large basins, whereas the Godavari, Krishna, Kaveri and Mahanadi flow east into the Bay of Bengal and the Narmada and Tapi flow west through rift valleys into the Arabian Sea.

Monsoon mechanism: differential heating of land and sea creates low pressure over the Indian landmass in summer; the ITCZ shifts north, the Tibetan Plateau heats and the tropical easterly jet and Somali jet strengthen the southwest monsoon, while the withdrawal phase runs roughly September to December.

Soils: black (regur) soil from Deccan lava retains moisture and suits cotton; red soil derives from crystalline igneous rock; laterite forms under heavy leaching in high-rainfall zones; alluvial soil covers the northern plains and is the most fertile.

Census concepts: birth rate and death rate are per 1,000 persons per year; natural growth equals births minus deaths; the sex ratio is females per 1,000 males; literacy counts persons aged 7 and above who can read and write with understanding.

Fundamental Rights (Part III) include equality (Articles 14–18), freedom (19–22), against exploitation (23–24), religion (25–28), cultural and educational rights (29–30) and constitutional remedies (32); the Right to Education was added by the 86th Amendment (2002) as Article 21A.

Directive Principles (Part IV, Articles 36–51) are non-justiciable; the Fundamental Duties were added by the 42nd Amendment (1976) on the Swaran Singh Committee's recommendation, and the 44th Amendment (1978) removed the right to property from Fundamental Rights, making it a legal right under Article 300A.

Indian economy basics: GDP is the market value of final goods and services produced within domestic territory in a year; GNP equals GDP plus net factor income from abroad; per capita income equals national income divided by population, and the primary, secondary and tertiary sectors are ranked by the share of employment versus the share of output.

Indian National Movement milestones: Partition of Bengal (1905) triggered the Swadeshi movement; Jallianwala Bagh (13 April 1919) preceded the Non-Cooperation Movement (1920–22), withdrawn after Chauri Chaura; the Simon Commission (1928) was boycotted; the Lahore session (1929) adopted Purna Swaraj and 26 January 1930 was observed as Independence Day.

The Dandi March (12 March–6 April 1930) began the Civil Disobedience Movement; the Gandhi–Irwin Pact (1931) and Second Round Table Conference followed; the Government of India Act 1935 introduced provincial autonomy, and the Quit India Movement was launched on 9 August 1942.

Earth's movements: rotation on its axis (west to east) takes about 24 hours and causes day and night; revolution around the Sun takes about 365¼ days and, with a 23½° axial tilt, causes seasons and the solstices and equinoxes.

Latitude lines run parallel and never meet; longitude lines converge at the poles and each 15° of longitude equals one hour of time difference; the International Date Line roughly follows 180° longitude.

Maps: scale is the ratio of map distance to ground distance; representative fraction, statement and graphical (linear) scale are the three forms; contours join points of equal elevation and closely spaced contours indicate steep slopes.

India's physiographic divisions: the Himalayas (young fold mountains), the Northern Plains (alluvial, formed by Indus, Ganga and Brahmaputra systems), the Peninsular Plateau (old crystalline shield), the Coastal Plains and the Islands (Andaman and Nicobar in the Bay of Bengal; Lakshadweep in the Arabian Sea, of coral origin).

Climate types in India: tropical monsoon (most of the country), semi-arid (Rajasthan, interior Deccan), tropical wet (Western Ghats windward slopes, northeast), humid subtropical (northern plains), and tundra/alpine in high Himalayas; Mawsynram and Cherrapunji record the highest rainfall.

Agriculture: kharif crops are sown with the southwest monsoon (June–October: rice, cotton, jowar, bajra, maize); rabi crops are sown in winter (October–March: wheat, gram, mustard); zaid is the short summer season (watermelon, cucumber, fodder).

Economic sectors: primary (agriculture, mining, fishing), secondary (manufacturing, construction) and tertiary (services such as trade, transport, banking); India's tertiary sector contributes the largest share of gross value added, while the primary sector still employs the largest share of workers.

National income measurement: Gross Domestic Product at market prices equals the sum of final expenditures (C + I + G + net exports) or the sum of factor incomes; Net National Product equals GNP minus depreciation; per capita income is a rough development indicator but ignores distribution and non-market work.

Human Development Index combines life expectancy, education (mean and expected years of schooling) and gross national income per capita; the Human Development Report is published by the United Nations Development Programme.

Poverty and employment: the poverty line is set from calorie norms and consumption expenditure; the Multidimensional Poverty Index measures health, education and living-standard deprivations; types of unemployment include seasonal, disguised, educated and structural.

Rights framework: civil liberties protect freedom of speech, assembly, association, movement, residence and profession (Article 19), subject to reasonable restrictions; preventive detention is limited by Article 22; rights are enforceable through courts, unlike Directive Principles.

Social movements and reform: the Brahmo Samaj (1828, Raja Ram Mohan Roy), Arya Samaj (1875, Dayanand Saraswati), Ramakrishna Mission (1897, Vivekananda), and the self-respect and anti-caste movements (Jyotirao Phule, B.R. Ambedkar) shaped modern Indian society.
