Trends and patterns in the structure of the population: growth rate is interesting to study. The growth rate implies the study of the number of people born. The global population growth rate is around                                                                                                             1.05%. The population is estimated to increase by around 81 million on average. The population growth rate is lower than the 1.08% recorded in 2019.. The article, therefore, has looked at various aspects of trends and patterns in the structure of the population: growth rate. It discusses factors that influence population fluctuation– Exponential growth &logistic growth. 

Trends and Patterns in the Structure of the Population: Growth Rate

Growth rate denotes a change in the percentage. This change is calculated over a period. growth rate is only one of the other trends and patterns. The article has primarily focused on studying Trends and patterns in the structure of the population: growth rate. Population growth is calculated on the total number of people being born and the migration that happens in a year . It is then divided by the number of the population at the commencement of the year. This falls under census and logistics. Statistics and data also include such numerical considerations. These datasets and statistical information are available for download on many websites. The population growth rate helps in understanding ecological, environmental, historical, socio-economic as well as socio-political aspects: Impacts of population growth can be traced:

• Resource of exploitation and extraction increases
• Fossil fuels are increasingly exhausted 
• Spread of invasive species as well as communicable diseases increases
• Different ecological systems get affected

Factors that Influence Population Fluctuation

Factors that influence population fluctuation have been discussed. Density is the greatest factor when it comes to determining the population fluctuations and is a part of Factors that influence population fluctuation. This determination of density is further divided into two parts. These are density-independent and dependent. The various factors are:

• Climatic conditions
• Mortality rates
• Growth rate
• Birth rate
• Medical facilities available
• Socio-political factors and Economic factors

Factors that influence population fluctuation can be varied. Many scholars and academicians have put forward different variations of these factors. The data gathered from this resource is helpful in many interdisciplinary fields and assists in determining factors that influence population fluctuation. 

Exponential Growth

Exponential growth is a type of population growth that is studied. Here, the Per individual percentage of the population remains steady despite the size. So exponential growth has an increasing curve. Exponential growth is very common in natural habitats. Due to facilities available for growth and development, there will be exponential growth. But at some point, it will be limited by the lack of dwindling resources to sustain it. Exponential growth, therefore, has some characteristics:

• Population increases dramatically
• Resources are available
• It is sustained for a brief time
• It is not realistic or manageable
• It lacks an upper limit

Logistic Growth

Environmental limits restrict sustained population growth. When population growth increases exponentially then a point reaches when the growth stops and starts declining. Then the curve is shaped like J in graphical representation. Logistic growth is when available resource starts restricting exponential growth so then the increase follows a logical part. Upon resources dwindling, population growth decreases. Logistic growth is a type of population growth rate. 

Conclusion

The population had been stable for a long time in global history. But it was disrupted due to the technological and scientific innovations made by humanity. As better medical facilities were made available for people that reduced mortality rates and sustained human lives, the population saw a marked increase. The growth rate studies changes brought on the environment. Population growth does impact the global ecosystem as well as climatic conditions dramatically.
