The MacroDemography Database is an ongoing project aimed combining long-run macroeconomic and demographic data in a readily usable format for researchers aiming to explore questions relating to the relationship between economies and their underlying age structure. By enriching the set of demographic variables used in long run economic analysis while taking advantage of the contribution of the contribution of the Jordà-Schularick-Taylor Macrohistory Database in providing a rich set of macroeconomic variables for a panel of countries it is possible to revisit many questions in the literature on the economic implications of population aging that were not possible in the past. My aim is to continue to update this database with various sources of demographic variable to improve the completeness of the panel over time. At present the data contains an unbalanced panel of 18 countries spanning the time period from 1870 to 2018. The dataset "MacroDemography.dta" is the main data, while "MacroDemography_wProjections" appends median variant projections for population data from 2020 to 2100. This dataset uses the following sources that should be cited when using the relevant statistics.

According to Cognitive Market Research, The Global Nano Fiber Scaffold market size is USD 1.1 billion in 2023 and will enhance at a compound annual growth rate (CAGR) of 5.90% from 2023 to 2030.

The demand for nanofiber scaffolds is rising due to increased environmental concerns and filtration applications.
Demand for polymeric nanofibers remains higher in the nanofiber scaffold market.
The electrospinning category held the highest nanofiber scaffold market revenue share in 2023.
North America will continue to lead, whereas the European Nano Fiber Scaffold market will experience the most substantial growth until 2030.

Rise in Aged Population to Provide Viable Market Output

The nanofiber scaffold market is experiencing growth due to the rise in the aged population. With an increasing number of elderly individuals worldwide, there is a heightened demand for advanced medical solutions to address age-related health issues. Nanofiber scaffolds are crucial in regenerative medicine and tissue engineering, offering enhanced support for cell growth and tissue regeneration. As the aging population continues to bolster, the need for innovative healthcare technologies grows, propelling the market for nanofiber scaffolds. These scaffolds hold promise in treating various age-related conditions, driving research, development, and adoption within the healthcare sector.

For instance, as per World Population Prospects by the United Nations, the overall population is likely to exceed 9.3 billion by 2050, and around 21% of the population is expected to be aged 60 and above.

Market Dynamics of Nano Fiber Scaffold

High Cost of Production to Restrict Market Growth

The nanofiber scaffold market faces a challenge due to the high cost of production. The intricate and advanced manufacturing processes in creating nanofiber scaffolds and utilizing cutting-edge technologies and expensive raw materials contribute to elevated production costs. This cost challenge poses a barrier to widespread adoption and market growth, limiting accessibility for various applications. Addressing these cost issues is crucial for the nanofiber scaffold market to attain broader acceptance and capitalize on its potential benefits in diverse fields such as tissue engineering and biomedical applications.

Optimization for vivo applications restrains the market growth 

Despite the significant potential of electrospun nanofibers in tissue engineering, several technical and translational challenges continue to restrain the growth of the nanofiber scaffold market. Most studies to date have been limited to in vitro environments, which do not fully replicate the complex biological systems found in vivo. As a result, polymeric nanofiber scaffolds still require substantial optimization in terms of both composition and structural design to be viable for clinical applications. One of the key hurdles is the development of 3D porous architectures that support effective cell infiltration, viability, and integration with host tissues. Moreover, for these scaffolds to fulfill their therapeutic promise, they must be engineered to incorporate cells and bioactive factors such as growth factors. While companies like Astellas Pharm...

It is estimated that more than 8 billion people live on Earth and the population is likely to hit more than 9 billion by 2050. Approximately 55 percent of Earth’s human population currently live in areas classified as urban. That number is expected to grow by 2050 to 68 percent, according to the United Nations (UN).The largest cities in the world include Tōkyō, Japan; New Delhi, India; Shanghai, China; México City, Mexico; and São Paulo, Brazil. Each of these cities classifies as a megacity, a city with more than 10 million people. The UN estimates the world will have 43 megacities by 2030.Most cities' populations are growing as people move in for greater economic, educational, and healthcare opportunities. But not all cities are expanding. Those cities whose populations are declining may be experiencing declining fertility rates (the number of births is lower than the number of deaths), shrinking economies, emigration, or have experienced a natural disaster that resulted in fatalities or forced people to leave the region.This Global Cities map layer contains data published in 2018 by the Population Division of the United Nations Department of Economic and Social Affairs (UN DESA). It shows urban agglomerations. The UN DESA defines an urban agglomeration as a continuous area where population is classified at urban levels (by the country in which the city resides) regardless of what local government systems manage the area. Since not all places record data the same way, some populations may be calculated using the city population as defined by its boundary and the metropolitan area. If a reliable estimate for the urban agglomeration was unable to be determined, the population of the city or metropolitan area is used.Data Citation: United Nations Department of Economic and Social Affairs.
