Meaning of “Non-existence”: In mathematics, the number “0 (zero)” can signify both “does not exist” and the transition of a filled unit to a higher one in the decimal system. The first meaning is connected to ontology, while the second explains how, when one decimal unit is full, the total shifts to the next unit, and a zero indicates this shift. In this system, zero marks that the next higher unit is present. Philosophically, the concept of “nothing” is viewed in the West as “non-existence,” but in the East, it can signify a transformation to the next level after being filled. So don’t be discouraged if you don’t have anything. Your “disappointment” also comes from the fact that other areas have already been filled. - Joseph’s “just my thoughts”
Even though a country's total population is decreasing, the economic situation could be improved by increasing the total economic activity of the remaining population after the decrease. Of course, there is a statistical population threshold below which this effect occurs. Nevertheless, this effect would not work in the case of a force majeure, such as a natural disaster or the outbreak of war, however, this assumption would be valid because a rapid population decline is a highly exceptional event that would not normally occur. Therefore, an increase in the economic activity of this population should be required during an economic recession. Applying this perspective, for building a solid relationship with your followers on Instagram, the number of followers is less important than the activity between them and you. This is called the "Engagement Rate (ER)". - Joseph’s “just my thoughts”
