Yes. But it depends on the kind of price in which it's measured. This all-inclusive growth of the economy is surely observed if the GDP is measured in constant price, not in nominal price.
No. Increase in GDP means that production increased. However, it does not tell you anything about how meaningful this increase was. For example, after the communism started in former Soviet Union, their economic growth was very strong. However, since they were producing a lot of useless stuff, it did not contribute to long-term growth.
But, we must remember that GDP is measured at the macroeconomic level. GDP and its positive growth can conceal enormous disparities if resource allocations are inappropriate and not focused on poverty reduction. It is like increasing the income of a household. This can happen without the members of the household being happy, if the resources are badly affected. If these resources are allocated, for example, to the purchase of cigarettes, alcohol, etc., to the acquisition of goods that are not relevant to the welfare of the members. It is therefore desirable to complement GDP and its growth rate with poverty indices (P0, P1 and P2) and inequality indices (Gini index, for example) that reflect how GDP growth spread its effects to the entire population.
