World Population Day, observed to raise awareness about global population issues, is celebrated every year on which date?

Introduction / Context:
This question is about World Population Day, an important observance that focuses on population issues such as family planning, gender equality, poverty and human rights. Its date is a common feature in general knowledge and demographic awareness questions.

Given Data / Assumptions:

• The observance is World Population Day.
• It is celebrated annually in July.
• Several dates in July are given, including the correct one.

Concept / Approach:
World Population Day aims to highlight the urgency and importance of population related issues. The approach to answering is:

• Recall that World Population Day is observed on 11th July each year.
• Use elimination to rule out other dates that fall near 11th July but are not associated with this observance.
• Select the correct date based on your demographic awareness readings.

Step-by-Step Solution:
Step 1: Recognise that the question is specifically about World Population Day. Step 2: Remember from demographic and general knowledge notes that World Population Day is observed on 11th July. Step 3: Look at the options and locate 11th July. Step 4: Note that 4th July is more commonly associated with the independence day of the United States, not population issues. Step 5: 7th, 9th and 15th July are included as near dates but do not correspond to this global observance. Step 6: Mark 11th July as the correct answer.

Verification / Alternative check:
Verification can be done using UN Population Fund (UNFPA) resources, United Nations calendars and standard yearbooks. These consistently state that World Population Day is observed on 11th July, often accompanied by reports, campaigns and data releases about population trends and challenges. News articles and awareness programmes on that date every year further confirm the association.

Why Other Options Are Wrong:
9th July: A nearby date in July but not linked with World Population Day. 15th July: Also not used for this observance. 4th July: Known primarily for the independence day of the United States, not for a UN population day. 7th July: Included as a distractor, but it is not the official date of World Population Day.

Common Pitfalls:
Learners may remember only that the day falls in early to mid July and then guess among the available dates, leading to errors. Others might confuse it with different July related observances or national holidays. To avoid this, try to associate 11th July with population themes, demographic statistics and the work of UNFPA, and revise that association whenever you study population and development topics.

Final Answer:
World Population Day is observed every year on 11th July.
